摘要

Compounds of formula: <CHEM> and stereoisomers and salts thereof, wherein R<1> and R<2>, which are the same or different, are optionally substituted alkyl; V is oxygen or sulphur; Y is hydrogen, optionally substituted alkyl, cyano, nitro or halogen; X is <CHEM> CH2NR<1><0>R<1><1> or @- R<1><2> Z is NOR<5> or @-B; A is CO2R<6>, COR<7>, cyano, nitro or acylamino; Bis hydrogen, optionally substituted alkyl, optionally substituted aryl, CO2R<8>, COR<9>, cyano, nitro or acylamino, or A and B together form a ring containing one or more heteroatoms; R<4> is CO2R<3> or R<1><7>; R<1><2> is OR<1><3>, SR<1><4>, NR<1><5>R<1><6> or R<1><8>; R<3> is optionally substituted alkyl; and R<5> to R<1><1> and R<1><3> to R<1><8>, which are the same or different, are hydrogen, optionally substituted alkyl, optionally substituted cycloalkyl, optionally substituted cycloalkylalkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted aralkyl, optionally substituted aryl or optionally substituted heteroaryl, or R<1><0> and R<1><1> or R<1><5> and R<1><6> together with their adjacent nitrogen atom join to form a saturated ring (except that R<1><0> and R<1><1>, together with their adjacent nitrogen atom, do not form an unsubstituted piperidine ring when R<1> and R<2> are both methyl, Y is hydrogen and V is oxygen) optionally containing one or more heteroatoms in addition to the nitrogen atom. The compounds are useful as fungicides and also as plant growth regulators, insecticides, nematocides and miticides.
