Abstract: The invention concerns chiral amino acid, is preparation method, and the use of said chiral amino acid as intermediate for the synthesis of chiral organic compounds.

Abstract: This invention relates to new herbicidal compositions comprising a mixture of (a) an alkoxypyrimidyloxybenzoic acid derivatives of formula (I): wherein X is a hydrogen atom or a group (C6H5)2C═N—, or an agriculturally acceptable salts thereof, for example alkali or alkaline earth metal salts and (b) a partner herbicide. This invention additionally relates to a method of controlling weeds comprising applying these new herbicidal compositions to a locus.

Abstract: The invention relates to compounds of formula (I), and also to salts thereof, which have fungicidal activities: in which the various radicals and substituents are as defined in the description, and also to the fungicidal compositions containing them and to methods for combating the phytopathogenic fungi of crops using these compounds and compositions.

Abstract: The invention concerns a novel method for preparing chiral amino acids of formula (I) characterised in that it consists in contracting a racemic hydantoin of formula (II) with an enantiomeric splitting agent.

Abstract: The invention concerns a novel composition comprising a herbicide of the glyphosate family, a herbicide of the isoxazole family and a biological activator, wherein the herbicide of the glyphosate family is selected among N-phosphomethylglycine (glyphosate acid), N-phosphomethylglycine alkaline metal salts, N-phosphomethylglycine ammonium salts and N-phosphomethylglycine trimethyisulphonium salts (sulphosate), and wherein the biological activator consists essentially of an ammonium sulphate. The invention also concerns a method for agronomic treatment of plants tolerant to glyphosate family herbicides and to isoxazole family herbicides to eliminate weeds which consists in applying in a field containing said tolerant plants an appropriate amount of the inventive composition.

Abstract: The invention relates to a process for the preparation of a compound of formula (I) wherein: R1 represents C1-4 haloalkyl, fluorine, chlorine or bromine; and R2 represents hydrogen or C1-4 alkoxy; which process comprises the reaction of the corresponding ortho-nitrohalobenzene of formula (II): wherein R1 and R2 are as hereinbefore defined and X represents a fluorine or bromine atom, with, when X represents a fluorine atom: (a) an alkali metal cyanide, in a non aqueous solvent, optionally in the presence of a catalyst; or when X represents a bromine atom: (b) cuprous cyanide, in a non aqueous solvent, optionally in the presence of a catalyst selected from an alkali metal bromide or an alkaline earth metal bromide; or (c) an alkali metal cyanide, in a non aqueous solvent, in the presence of a catalytic amount of cuprous cyanide and a phase transfer catalyst.

Abstract: The present invention relates to DNA molecules of plant origin encoding a modified 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) enzyme wherein the a first EPSPS coding sequence that normally encodes a threonine residue of a mature EPSPS sequence is modified to encode isoleucine of the mature EPSPS sequence, and a second EPSPS coding sequence that normally encodes a proline residue of a mature EPSPS sequence is modified to encode serine of the mature EPSPS sequence, wherein the first and second residues are respectively located at relatively positions 102 and 106 of a mature EPSPS sequence encoded by said DNA molecule; and the production of a transgenic plant resistant or tolerant to a herbicide of the phosphonomethylglycine family, e.g., glyphosate.

Abstract: The invention provides the use as a pesticidal adjuvant of at least one citric acid derivative and compositions containing the derivative, which has a log octanol-water coefficient (log P) of 2.6 to 11 and an equivalent hydrocarbon (EH) value of 29 to 47. The invention has been shown to enhance the efficacy of a range of pesticides.
