ABSTRACT:
The invention provides a process for the preparation of cyclopentanediol derivatives of the general formula ##STR1## in which n represents an integer from 0 to 5; each R represents a halogen atom, nitro, cyano, hydroxyl, alkyl, haloalkyl, alkoxy, haloalkoxy, amino, alkylamino, dialkylamino, alkoxycarbonyl, carboxyl, alkanoyl, alkylthio, alkylsulphinyl, alkylsulphonyl, carbamoyl, alkylamido, cycloalkyl or phenyl group; and R.sup.1, R.sup.2 and R.sup.3 independently represent a hydrogen atom or an alkyl group; which comprises reacting a cyclopentanol derivative of the general formula ##STR2## with a reducing agent. The invention also provides the cyclopentanol derivative intermediates of formula II per se and a process for their preparation. Compounds of formulae I and II are useful as intermediates in the preparation of certain fungicidally active cyclopentane derivatives.
