Description

The invention relates to novel optically active 2,5-bisaryl-Δ1-pyrrolines, processes for their preparation and to their use as pesticides.

Racemic Δ1-pyrroline pesticides have already been described in WO 00/21958, WO 99/59968, WO 99/59967 and WO 98/22438.

However, the efficacy and/or duration of action of these prior-art racemates is, in particular against certain organisms and/or at low application rates, not entirely satisfactory in all areas of use.

Owing to the multifarious requirements that modern pesticides have to meet, for example with respect to efficacy, duration of action, activity spectrum, use spectrum, toxicity, combination with other active compounds, combination with formulation auxiliaries or synthesis, and owing to the possible occurrence of resistance, however, the development of such substances can never be considered as being concluded, and there is always a great need for novel compounds which, at least in some aspects, offer advantages over the known compounds.

It is an object of the present invention to provide optically active compounds of the general formula (I). When used as pesticides, these compounds allow the application rates to be reduced.

The present invention provides novel optically active Δ1-pyrrolines of the formula (I)

The formula (VII-rac) provides a general definition of the racemic lactams required as starting materials for carrying out the Process γ. In this formula, R3, R4 and m each preferably, particularly preferably and very particularly preferably have those meanings which have already been mentioned in connection with the compounds of the formula (I) according to the invention as being preferred, particularly preferred etc. for these radicals.

Racemic lactams of the formula (VII-rac) are known and can be prepared by known processes (WO 99/59968, WO 99/59967 and WO 98/22438).

When carrying out the Process γ, methods of preparative chromatography, preferably the High Performance Liquid Chromatography (HPLC) method, are employed. Here, a chiral stationary silica gel phase is used. A silica gel derivative (for example mercaptopropyl silica gel) modified with N-methacryloyl-L-leucin-D-menthylamide has been found to be particularly suitable for separating the compounds of the formula (VII-rac) (cf. EP-A 0 379 917).

Surprisingly, the racemic lactams of the formula (VII-rac) can be separated on a kg scale in a short period of time (gradients shorter than 20 min) by repeated chromatography on relatively short columns [450 mm×75 mm, (I.D.)], this process thus also being suitable for industrial use. Compared to commercial stationary chiral phases, the material used has considerably higher enantioselectivity values α(α=16 as compared to α=3 to 4; the higher the α value, the better the separation of the enantiomers).

The multi-step Process δ according to the invention can be illustrated by the equation below.

γ-Ketocarboxylic acids of the formula (VIII) are condensed with 2(S)-2-amino-2-phenylethanol to give bicyclic lactams of the formula (IX) which are predominantly obtained as one diastereomer.

Reductive cleavage of bicyclic lactams of the formula (IX) using a Lewis acid (for example TiCl4) and a reducing agent (for example Et3SiH) gives N-protected γ-lactams of the formula (X) (cf. J. Org. Chem. 1992, 57, 1656).

The hydroxyl group in γ-lactams of the formula (X) can be converted into a leaving group (in particular a chlorine atom, cf. Tetrahedron Asymmetry 1996, 7, 1835) using a chlorinating agent (for example thionyl chloride), giving chlorides of the formula (XI).

Dehydrohalogenation of (XI) by treatment with a base (for example KOtBu) gives N-vinyllactams of the formula (XII).

It is also possible to convert γ-lactams of the formula (X) directly, for example by treatment with a base (for example LiOH) in a suitable solvent (for example DMSO) at temperatures between 60° C. and 140° C. into the N-vinyllactams of the formula (XII) (cf. J. Org. Chem. 1996, 61, 5813).

Acid-promoted hydrolysis of (XII) (using, for example, 1 M HCl) gives γ-lactams of the formula (VII) (cf. J. Org. Chem. 1996, 61, 5813).

The formula (VIII) and the formulae (IX), (X), (XI) and (XII) provide general definitions of the γ-ketocarboxylic acids required as starting materials for carrying out the Process δ according to the invention and the intermediates, respectively. In these formulae, R3, R4 and m each preferably, particularly preferably and very particularly preferably have those meanings which have already been mentioned in connection with the description of the compounds of the formula (I) according to the invention as being preferred, particularly preferred etc. for these radicals.

Some of the γ-ketocarboxylic acids of the formula (VIII) are known. Some of the methods by which they can be prepared are known. γ-Ketocarboxylic acids of the formula (VIII) are obtained, for example, by reacting appropriate aromatics with succinic anhydride or succinic acid monoester chloride in the presence of a Lewis acid (for example aluminium chloride) and, if appropriate, in the presence of a diluent (for example 1,2-dichlorethane) (cf., for example, Org. Prep. Proced. Int. 1995, 27, 550-552).

In the case of aromatics which do not permit a Friedel-Crafts acylation, it is alternatively possible to use a corresponding organometallic derivative, such as, for example, a Grignard reagent (cf. Syn. Commun. 1996, 26, 3897).

It is also possible to prepare γ-ketocarboxylic acids of the formula (VIII) by reducing α,β-unsaturated carbonyl compounds of the formula (XIII) using, for example, Zn dust in glacial acetic acid according to the reaction scheme below (cf. Chem. Pharm. Bull. 1988, 36, 2050).

The formula (XIII) provides a general definition of the carbonyl compounds. In this formula, R3, R4 and m each preferably, particularly preferably and very particularly preferably have those meanings which have already been mentioned in connection with the description of the compounds of the formula (I) according to the invention as being preferred, particularly preferred etc. for these radicals.

Some of the α,β-unsaturated carbonyl compounds of the formula (XIII) are known, and/or they can be prepared, for example, by condensing acetophenones of the formula (XIV) with glyoxalic acid in the presence of a base (for example NaOH) and, if appropriate, in the presence of a diluent (for example water, EtOH) according to the reaction scheme below (cf., for example, J. Med. Chem. 1996, 39, 4396).

The formula (XIV) provides a general definition of the acetophenones. In this formula, R3, R4 and m each preferably, particularly preferably and very particularly preferably have those meanings which have already been mentioned in connection with the description of the compounds of the formula (I) according to the invention as being preferred, particularly preferred etc. for these radicals. Acetophenones of the formula (XIV) are known.

The multi-step Process ε can be illustrated by the equation below.

The reaction of a γ-ketocarboxylic ester of the formula (VIII-a) with allylamine in the presence of ammonium chloride gives allylamides of the formula (XV) (cf. Houben-Weyl, Methoden der Organischen Chemie [Methods of Organic Chemistry], 4th Edition, Volume VIII, Chapter 6, p. 653 ff.).

According to the Corey, Bakshi & Shibata protocol (CBS reduction), the ketofunctionality in compounds of the formula (XV) can be enantioselectively reduced in the presence of a catalyst {for example (3aR)-1-methyl-3,3,6-triphenyltetrahydro-3H-pyrrolo[1,2-c][1,3,2]oxazaborol, commercially available} (cf. Angew. Chem. 1998, 110, 2093 and references cited therein).

The subsequent cyclization of compounds of the formula (XVI) to give N-allyllactams of the formula (XVII) can be carried out by double-deprotonation with KOtBu and reaction with tosyl chloride (cf. Synth. Commun. 1988, 18, 1159), without noticeable loss of stereochemical information. In contrast to the literature reference, it is surprisingly possible to dispense with the use of the carcinogenic hexamethylphosphoric triamide (HMPT) cosolvent.

The allyl protective group is removed in an aqueous THF solution in the presence of toluenesulphonic acid with the addition of 10 mol % of Pd(Ph3P)4 (cf. Heterocycles 1997, 44, 213 and references cited therein), giving the lactam of the formula (VII). The desired enantiomer can be enriched by recrystallization from petroleum ether (40/60)/toluene.

The formula (VIII-a) and the formulae (XV), (XVI) and (XVII) provide general definitions of the γ-ketocarboxylic esters required as starting materials for carrying out the Process ε according to the invention and the intermediates, respectively. In these formulae, R3, R4 and m each preferably, particularly preferably and very particularly preferably have those meanings which have already been mentioned in connection with the description of the compounds of the formula (I) according to the invention as being preferred, particularly preferred etc. for these radicals.

γ-Ketocarboxylic esters of the formula (VIII-a) can be prepared from the corresponding acids of the formula (VIII) by known esterification processes.

If appropriate, they can also be employed as intermediates or precursors for the synthesis of other active compounds.

All plants and plant parts can be treated in accordance with the invention. Plants are to be understood as meaning in the present context all plants and plant populations such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional plant breeding and optimization methods or by biotechnological and recombinant methods or by combinations of these methods, including the transgenic plants and including the plant cultivars protectable or not protectable by plant breeders' rights. Plant parts are to be understood as meaning all parts and organs of plants above and below the ground, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruit bodies, fruits, seeds, roots, tubers and rhizomes. The plant parts also include harvested material, and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offsets and seeds.

Treatment according to the invention of the plants and plant parts with the active compounds is carried out directly or by allowing the compounds to act on the surroundings, environment or storage space by the customary treatment methods, for example by immersion, spraying, evaporation, fogging, scattering, painting on and, in the case of propagation material, in particular in the case of seeds, also by applying one or more coats.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound and microencapsulations in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants, and/or foam-formers.

If the extender used is water, it is also possible to employ for example organic solvents as auxiliary solvents. Essentially, suitable liquid solvents are: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols such as butanol or glycol and also their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, and also water.

As solid carriers there are suitable:

for example ammonium salts and ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates; as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and also synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks;
as emulsifiers and/or foam-formers there are suitable: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and also protein hydrolysates;
as dispersants there are suitable: for example lignosulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention can be used as such or in their formulations, as a mixture with other, also known active compounds, such as insecticides, attractants, sterilizing agents, bactericides, acaricides, nematicides, fungicides, growth-regulating substances or herbicides, in order, in this way, for example, to broaden the spectrum of activity or to prevent the development of resistance. In many cases, synergistic effects are obtained, i.e. the activity of the mixture exceeds the activity of the individual components. The insecticides include, for example, phosphoric acid esters, carbamates, carboxylates, chlorinated hydrocarbons, phenylureas and substances produced by microorganisms, inter alia.

It is also possible to admix other known active compounds, such as herbicides, fertilizers and growth regulators.

When used as insecticides, the active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the action of the active compounds according to the invention, without it being necessary for the synergistic agent added to be active itself.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

The compounds are employed in a customary manner appropriate for the use forms.

When used against hygiene pests and pests of stored products, the active compound is distinguished by an excellent residual action on wood and clay as well as a good stability to alkali on limed substrates.

As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The term “parts” or “parts of plants” or “plant parts” has been explained above.

Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are to be understood as meaning plants having certain properties (“traits”) which have been obtained by conventional breeding, by mutagenesis or by genetic engineering. These can be cultivars, bio- or genotypes.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances and compositions to be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.

The transgenic plants or plant cultivars (i.e. those obtained by genetic engineering) which are preferably to be treated according to the invention include all plants which, in the genetic modification, received genetic material which imparted particularly advantageous useful traits to these plants. Examples of such traits are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such properties are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, cotton, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to maize, soya beans, potatoes, cotton and oilseed rape. Traits that are emphasized are in particular increased defence of the plants against insects by toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as “Bt plants”). Traits that are also particularly emphasized are the increased defence of the plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and corresponding expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosates or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combination with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya beans), KnockOut® (for example maize), StarLink® (for example maize), Bollgard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya bean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulphonylurea, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant cultivars having these genetic traits or genetic traits still to be developed, which plants will be developed and/or marketed in the future.

The plants listed can be treated according to the invention in a particularly advantageous manner with the compounds of the formula (I) and/or the active compound mixtures according to the invention. The preferred ranges stated above for the active compounds and/or mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or mixtures specifically mentioned in the present text.

The active compounds according to the invention act not only against plant, hygiene and stored product pests, but also in the veterinary medicine sector against animal parasites (ectoparasites), such as hard ticks, soft ticks, mange mites, leaf mites, flies (biting and licking), parasitic fly larvae, lice, hair lice, feather lice and fleas. These parasites include:

From the order of the Anoplurida, for example, Haematopinus spp., Linognathus spp., Pediculus spp., Phtirus spp. and Solenopotes spp.
From the order of the Mallophagida and the suborders Amblycerina and Ischnocerina, for example, Trimenopon spp., Menopon spp., Trinoton spp., Bovicola spp., Werneckiella spp., Lepikentron spp., Damalina spp., Trichodectes spp. and Felicola spp.

From the order of the Blattarida, for example Blatta orientalis, Periplaneta americana, Blattella germanica and Supella spp.
From the subclass of the Acaria (Acarida) and the orders of the Meta- and Mesostigmata, for example, Argas spp., Ornithodorus spp., Otobius spp., Ixodes spp., Amblyomma spp., Boophilus spp., Dermacentor spp., Haemophysalis spp., Hyalomma spp., Rhipicephalus spp., Dermanyssus spp., Raillietia spp., Pneumonyssus spp., Sternostoma spp. and Varroa spp.
From the order of the Actinedida (Prostigmata) und Acaridida (Astigmata), for example, Acarapis spp., Cheyletiella spp., Ornithocheyletia spp., Myobia spp., Psorergates spp., Demodex spp., Trombicula spp., Listrophorus spp., Acarus spp., Tyrophagus spp., Caloglyphus spp., Hypodectes spp., Pterolichus spp., Psoroptes spp., Chorioptes spp., Otodectes spp., Sarcoptes spp., Notoedres spp., Knemidocoptes spp., Cytodites spp. and Laminosioptes spp.

They have, for example, excellent activity against the development stages of ticks such as, for example, Amblyomma hebraeum, and against parasitic flies such as, for example, Lucilia cuprina.

The active compounds of the formula (I) according to the invention are also suitable for controlling arthropods which infest agricultural productive livestock, such as, for example, cattle, sheep, goats, horses, pigs, donkeys, camels, buffalo, rabbits, chickens, turkeys, ducks, geese and bees, other pets, such as, for example, dogs, cats, caged birds and aquarium fish, and also so-called test animals, such as, for example, hamsters, guinea pigs, rats and mice. By controlling these arthropods, cases of death and reduction in productivity (for meat, milk, wool, hides, eggs, honey etc.) should be diminished, so that more economic and easier animal husbandry is possible by use of the active compounds according to the invention.

The active compounds according to the invention are used in the veterinary sector in a known manner by enteral administration in the form of, for example, tablets, capsules, potions, drenches, granules, pastes, boluses, the feed-through process and suppositories, by parenteral administration, such as, for example, by injection (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal administration, by dermal use in the form, for example, of dipping or bathing, spraying, pouring on and spotting on, washing and powdering, and also with the aid of moulded articles containing the active compound, such as collars, ear marks, tail marks, limb bands, halters, marking devices and the like.

When used for cattle, poultry, pets and the like, the active compounds of the formula (I) can be used as formulations (for example powders, emulsions, free-flowing compositions), which comprise the active compounds in an amount of 1 to 80% by weight, directly or after 100 to 10 000-fold dilution, or they can be used as a chemical bath.

It has furthermore been found that the compounds according to the invention have a strong insecticidal action against insects which destroy industrial materials.

The following insects may be mentioned as examples and as preferred—but without a limitation:

Beetles, such as
Hylotrupes bajulus, Chlorophorus pilosis, Anobium punctatum, Xestobium rufovillosum, Ptilinus pecticomis, Dendrobium pertinex, Emobius mollis, Priobium carpini, Lyctus brunneus, Lyctus africanus, Lyctus planicollis, Lyctus linearis, Lyctus pubescens, Trogoxylon aequale, Minthes rugicollis, Xyleborus spec., Tryptodendron spec., Apate monachus, Bostrychus capucins, Heterobostrychus brunneus, Sinoxylon spec., Dinoderus minutus.
Hymenopterons, such as
Sirex juvencus, Urocerus gigas, Urocerus gigas taignus, Urocerus augur.
Termites, such as
Kalotermes flavicollis, Cryptotermes brevis, Heterotermes indicola, Reticulitermes flavipes, Reticulitermes santonensis, Reticulitermes lucifugus, Mastotermes darwiniensis, Zootermopsis nevadensis, Coptotermes formosanus.
Bristletails, such as Lepisma saccarina.

Industrial materials in the present connection are to be understood as meaning non-living materials, such as, preferably, plastics, adhesives, sizes, papers and cards, leather, wood and processed wood products and coating compositions.

Wood and processed wood products are materials to be protected, especially preferably, from insect infestation.

Wood and processed wood products which can be protected by the agents according to the invention or mixtures comprising these are to be understood as meaning, for example:

building timber, wooden beams, railway sleepers, bridge components, boat jetties, wooden vehicles, boxes, pallets, containers, telegraph poles, wood panelling, wooden windows and doors, plywood, chipboard, joinery or wooden products which are used quite generally in house-building or in building joinery.

The active compounds according to the invention can be used as such, in the form of concentrates or in generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersing agent and/or binder or fixing agent, a water repellent, if appropriate siccatives and UV stabilizers and if appropriate dyestuffs and pigments, and also other processing auxiliaries.

The insecticidal compositions or concentrates used for the preservation of wood and wood-derived timber products comprise the active compound according to the invention in a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of the compositions or concentrates employed depends on the nature and occurrence of the insects and on the medium. The optimum amount employed can be determined for the use in each case by a series of tests. In general, however, it is sufficient to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be preserved.

Solvents and/or diluents which are used are an organic chemical solvent or solvent mixture and/or an oily or oil-like organic chemical solvent or solvent mixture of low volatility and/or a polar organic chemical solvent or solvent mixture and/or water, and if appropriate an emulsifier and/or wetting agent.

Organic chemical solvents which are preferably used are oily or oil-like solvents having an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C. Substances which are used as such oily or oil-like water-insoluble solvents of low volatility are appropriate mineral oils or aromatic fractions thereof, or solvent mixtures containing mineral oils, preferably white spirit, petroleum and/or alkylbenzene.

Mineral oils having a boiling range from 170 to 220° C., white spirit having a boiling range from 170 to 220° C., spindle oil having a boiling range from 250 to 350° C., petroleum and aromatics having a boiling range from 160 to 280° C., terpentine oil and the like, are advantageously employed.

In a preferred embodiment, liquid aliphatic hydrocarbons having a boiling range from 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons having a boiling range from 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably α-monochloronaphthalene, are used.

The organic oily or oil-like solvents of low volatility which have an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., can be replaced in part by organic chemical solvents of high or medium volatility, provided that the solvent mixture likewise has an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

According to a preferred embodiment, some of the organic chemical solvent or solvent mixture is replaced by an aliphatic polar organic chemical solvent or solvent mixture. Aliphatic organic chemical solvents containing hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters or the like, are preferably used.

Organic chemical binders which are used in the context of the present invention are the synthetic resins and/or binding drying oils which are known per se, are water-dilutable and/or are soluble or dispersible or emulsifiable in the organic chemical solvents employed, in particular binders consisting of or comprising an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenolic resin, hydrocarbon resin, such as indene-comarone resin, silicone resin, drying vegetable oils and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances can also be used as binders in an amount of up to 10% by weight. Dyestuffs, pigments, water-repelling agents, odour correctants and inhibitors or anticorrosive agents and the like which are known per se can additionally be employed.

It is preferred according to the invention for the composition or concentrate to comprise, as the organic chemical binder, at least one alkyd resin or modified alkyd resin and/or a drying vegetable oil. Alkyd resins having an oil content of more than 45% by weight, preferably 50 to 68% by weight, are preferably used according to the invention.

All or some of the binder mentioned can be replaced by a fixing agent (mixture) or a plasticizer (mixture). These additives are intended to prevent evaporation of the active compounds and crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of the binder employed).

The plasticizers originate from the chemical classes of phthalic acid esters, such as dibutyl, dioctyl or benzyl butyl phthalate, phosphoric acid esters, such as tributyl phosphate, adipic acid esters, such as di-(2-ethylhexyl) adipate, stearates, such as butyl stearate or amyl stearate, oleates, such as butyl oleate, glycerol ethers or higher molecular weight glycol ethers, glycerol esters and p-toluenesulphonic acid esters.

Fixing agents are based chemically on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether or ketones, such as benzophenone or ethylenebenzophenone.

Possible solvents or diluents are, in particular, also water, if appropriate as a mixture with one or more of the abovementioned organic chemical solvents or diluents, emulsifiers and dispersing agents.

Particularly effective preservation of wood is achieved by impregnation processes on a large industrial scale, for example vacuum, double vacuum or pressure processes. The ready-to-use compositions can also comprise other insecticides, if appropriate, and also one or more fungicides, if appropriate.

Possible additional mixing partners are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in this document are an explicit constituent of the present application.

Especially preferred mixing partners which may be mentioned are insecticides, such as chlorpyriphos, phoxim, silafluofin, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron, transfluthrin, thiacloprid, methoxyfenozide and triflumuron, and also fungicides, such as epoxyconazole, hexaconazole, azaconazole, propiconazole, tebuconazole, cyproconazole, metconazole, imazalil, dichlorfluanid, tolylfluanid, 3-iodo-2-propinyl-butyl carbamate, N-octyl-isothiazolin-3-one and 4,5-dichloro-N-octylisothiazolin-3-one.

The compounds according to the invention can at the same time be employed for protecting objects which come into contact with saltwater or brackish water, such as hulls, screens, nets, buildings, moorings and signalling systems, against fouling.

Fouling by sessile Oligochaeta, such as Serpulidae, and by shells and species from the Ledamorpha group (goose barnacles), such as various Lepas and Scalpellum species, or by species from the Balanomorpha group (acorn barnacles), such as Balanus or Pollicipes species, increases the frictional drag of ships and, as a consequence, leads to a marked increase in operation costs owing to higher energy consumption and additionally frequent residence in the dry dock.

PREPARATION EXAMPLES Processs A Racemate Resolution: Δ1-Pyrrolines of the Formula (I)

(+/−)-5-(2,6-Difluorophenyl)-2-[4′-(trifluoromethoxy)-1,1′-biphenyl-4-yl]-3,4-dihydro-2H-pyrrole (I-3) (8 g) is dissolved in 1 l of n-heptane/isopropanol 9:1 (v/v=volume/volume). The solution is then fractionally chromatographed on the silica gel phase Chiralcel OD® [manufacturer: Daicel (Japan), column dimensions: 500 mm×40 mm (I.D.), particle size: 20 μm, flow rate: 40 m/min] by High Performance Liquid Chromatography using the mobile phase n-heptane/isopropanol 9:1 (v/v). To resolve the total amount, every 30 min 5 ml (corresponding in each case to 40 mg of the racemate) are applied to the column. The compounds are detected using a UV detector, at a wavelength of 254 nm. Following analysis for enantiomeric purity, the appropriate eluate fractions are pooled and substantially concentrated under reduced pressure and the residues are filtered off and, after washing with n-heptane, dried. The resulting crude product is purified on silica gel (mobile phase: n-hexane/ethyl acetate, 1:9→1:4, in each case v/v).

Process γ Preparation of the Optically Active Lactams of the Formula (VII) by Racemate Resolution

The racemate is resolved at room temperature by liquid chromatography on the chiral stationary polyamide silica gel phase using the eluent ethyl acetate and photometric detection. The chiral phase used is based on the monomer N-methacryloyl-L-leucine-d-menthylamide which, after free-radical polymerization, is covalently attached to a modified silica gel. Phases of this type are described, for example, in EP-A 0 379 917. Under the conditions given above, the dextrirotatory enantiomer elutes first.

Stationary phase: 1000 g of silica gel CSP; 10 μm, as described above Column: 450 mm × 75 mm Eluent: Ethyl acetate Flow rate: 100 ml/min UV detection: 254 nm Sample application: 6 g of racemate (= 150 ml of a solution of 40 g of racemate in 1 l of ethyl acetate)

The chromatographic separation conditions are set such that elution of the second enantiomer is accelerated by a short gradient with 100% methanol, thus reducing the total elution time considerably.

Following analysis for enantiomeric purity, the appropriate eluate fractions are pooled and substantially concentrated under reduced pressure and the residues are filtered off and, after washing with n-heptane, dried.

The enantiomeric purities of the lactams of the formula (VII) are determined by HPLC as follows:
