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.
本发明提供了一般式为##STR1##的环戊烷衍生物,其中n代表0至5的整数,每个R代表卤素原子、硝基、氰基、羟基、烷基、卤代烷基、烷氧基、卤代烷氧基、氨基、烷基氨基、二烷基氨基、烷氧羰基、羧基、烷酰基、烷硫基、烷基磺酰基、烷基磺酸基、氨基甲酰基、环烷基或苯基,R.sup.1和R.sup.2分别表示氢原子或烷基,R.sup.3表示可选取代的烷基或芳基;以及其制备方法。式I、II和IV的化合物在制备某些具有杀真菌活性的环戊烷衍生物的中间体方面是有用的。此外,某些式IV的化合物本身具有杀真菌活性。
