PROCESS FOR PREPARING CIS-5-[1-(4-CHLOROPHENYL)-METHYLENE]-1-HYDROXYMETHYL-2,2-DIMETHYLCYCLOPENTANOL

The present invention relates to a process for preparing a diol of the formulae (la) (lb), or a mixture thereof, comprising the reaction of an epoxy alcohol of formulae (Va) or (Vb), or a mixture thereof, with alkali metal borohydride or earth alkaline borohydride, in particular sodium borohydride, and anhydrous aluminum(lll) chloride. The invention also relates to processes and intermediates for preparing an epoxy alcohol of formulae (Va) or (Vb). The invention furthermore relates to processes for preparing cis-metconazole in which a diol of the formulae (la) or (lb) is applied as a precursor.

Azolylmethyloxabicyclohexane derivatives and fungicidal compositions thereof

Disclosed herein is a process for preparing a cis-azole derivative represented by the general formula (I) STR1 wherein R1 and R2 denote each a hydrogen atom or an alkyl group, R denotes a halogen atom, a nitro group, a cyano group, an alkyl group, a haloalkyl group or a phenyl group, A denotes a nitrogen atom or a methine group, and n stands for an integer of 1-5, which comprises reducing an azolylmethyloxabicyclohexane derivative represented by the general formula (VI) STR2 wherein R1, R2, R, A and n have the same meanings as defined above. A fungicidal composition comprising the azolylmethyloxabicyclohexane derivative represented by the above-mentioned general formula (VI) is also desclosed.
