ABSTRACT:
The invention provides cyclopentane 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, alkythio, alkysulphinyl, alkylsulphonyl, carbamoyl, alkylamindo, cycloalkyl or phenyl group, R.sup.1 and R.sup.2 independently represent a hydrogen atom or an alkyl group, and R.sup.3 represents an optionally substituted alkyl or aryl group; and a process for their preparation. Compounds of formulae I, II and IV are useful as intermediates in the preparation of certain fungicidally active cyclopentane derivatives. Also, certain compounds of formula IV are themselves fungicidally active.
