摘要

Compounds of general formula (I) are excellent bacteriocides exhibiting wide bacteriocidal spectra, wherein R1 is a heterocyclic group, CHO or CH¿2?OR?6; R2¿ is alkyl; R3 is hydrogen, alkyl, alkoxy, halogeno, nitro, cyano or haloalkyl; R4 is hydrogen, alkyl, cycloalkyl, alkoxyalkyl, alkoxycarbonyl, cyano, haloalkyl, aryl or a heterocyclic group; R5 is hydrogen, alkyl, cycloalkyl, alkenyl, alkynyl, alkanoyl, aroyl, alkoxycarbonyl, aryl or a heterocyclic group; A is (1) -CH¿2?ON=C(R?7¿)-, (2) -CH¿2?N(R?8)-N=C(R7¿), (3) -CH=NOC(R9)(R10)- or (4) -CH=NN=C(R7)-; B is oxygen or NR11; each wavy line refers to the configuration of an E- or Z-isomer or a mixture of both.
