  • Patent number: 6369099
    Abstract: A method of modifying or altering the structure of a 1&agr;-hydroxylated vitamin D compound to increase its biological activity by altering the conformational equilibrium of the A-ring to favor a chair conformation that presents the 1&agr;-hydroxyl in the axial orientation. This is accomplished by either locking the A-ring chair conformation in a geometry having an axially orientated 1&agr;-hydroxyl, or by the addition of one or more substituents to the A-ring which interact with other substituents in the molecule or on the A-ring to provide a driving force to the A-ring to adopt a chair conformation which presents the 1&agr;-hydroxyl in the axial orientation.

    Abstract: The present invention regards a three-step process for the synthesis of 5-(&agr;-hydroxyalkyl) benzo[1,3]dioxols. The process comprises: (i) the reaction of pyrocatechin (1,2-dihydroxybenzene) with a dihalo or di-alkoxyalkane, with the formation of a benzo[1,3]dioxol derivative; (ii) 5-selective catalytic acylation of the benzo[1,3]dioxol, with formation of a 5-alkanoylbenzo[1,3]dioxol and its subsequent (iii) reduction to 5-(&agr;-hydroxyalkyl) benzo[1,3]dioxol. Also described are new benzodioxols obtainable using the above-mentioned process. The process of the invention is industrially simple and has low environmental impact; it allows to obtain in high yields derivatives of considerable interest, in particular for the perfumery industry, and in the sector of insecticides.

  • Patent number: 5670665
    Abstract: According to the invention, a new process for the preparation of fluorine-substituted aminobenzodioxoles and -benzodioxanes of the formula (I) ##STR1## in which n represents an integer 1 or 2, has been found, in which fluorine-substituted nitro-halogeno-benzodioxoles and -benzodioxanes, which are likewise new, are hydrogenated. The novel intermediates are obtained from fluorine-substituted benzodioxoles and benzodioxanes by halogenation and subsequent nitration. The amino compounds are important starting materials for highly active biocides.

  • Patent number: 5637737
    Abstract: 2,2-Difluorobenzo[1.3]dioxole-carbaldehydes are prepared in a particularly advantageous manner if methylbenzo[1.3]dioxoles are chlorinated, the resulting dichloromethyl-2,2-dichlorobenzo[1.3]dioxole is fluorinated with hydrogen fluoride and the dichloromethyl-2,2-difluorobenzo[1.3]dioxole obtained by this procedure is reacted with a carboxylic acid.

  • Patent number: 5599952
    Abstract: Methods of producing carboxylic acid ester derivatives of formulae (I) and (II), which are useful, for instance, as intermediates for producing an anti-hypercholesterolemic agent having an inhibitory effect on HMG-CoA Reductase: ##STR1## wherein R.sup.1 and R.sup.2 are independently a protective group for hydroxyl group, or R.sup.1 and R.sup.2 integrally constitute a protective group for hydroxyl groups; R.sup.3 is an alkyl group, or an aryl group; and R.sup.4 is a substituted aryl group, a substituted heterocyclic group, a substituted vinyl group, or a substituted cycloalkenyl group; and ##STR2## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are respectively the same as defined in the above formula (I), are disclosed. In addition, intermediates for use in these methods of producing the carboxylic acid ester derivatives are disclosed.
