【摘要】 4-取代-1-甲基-3-乙基-5-吡唑甲酰肼与氯甲酸酯缩合得到16个1-吡唑酰基-2-烷氧基羰基肼类化合物(2a~2h和3a~3h,其中14个是新化合物),其结构经1H NMR,IR,MS和元素分析表征。初步生物活性测试结果表明,当浓度为500μg.mL-1时,3a,3b和3 e对油菜菌核病菌抑制活性均达到90%,3d对小麦白粉病菌的抑制活性达到90%;2h对蚕豆蚜的抑制活性达到92.75%。当浓度为1 000μg.mL-1时,2h对粘虫的抑制活性达到100%。更多还原

【Abstract】 1-Pyrazol-5′-ylcarbonyl-2-（alkyloxycarbonyl）hydrazides（2a²h and 3a³h,fourteen of them are novel compounds） were synthesized by a（condensation） reaction of 4-substituted-3-ethyl-1-methyl-5-pyrazole formhydrazide with chloroformate.Their structures were confirmed by ¹H NMR,IR,MS and elemental analysis.The biological activity tests showed that 3a,3b and 3e exhibited excellent inhibitory activities（90%） against（sclerotinia） sclerotiorum,inhibitory activity of 3d was 90% against blumeria graminis,inhibitory activity of 2h was 92.75% against aphis fabae as 500 μg·mL^-1;2h exhibited（excellent） inhibitory activity（100%） against mythimna separate as 1 000 μg·mL¹.更多还原
