为了寻找具有较好生物活性的吡唑肟醚衍生物,采用活性亚拼接方法,设计并合成了一系列新型含取代吡唑环结构的吡唑肟醚类化合物.通过1H NMR、13C NMR和元素分析等手段对目标化合物的结构进行了表征.初步的生物活性测试结果表明,大多数化合物表现出较好的杀虫活性.在测试浓度为500 μg/mL时,16个化合物对粘虫的杀灭活性可达80%~100%,14个化合物对蚜虫的杀死率可达80%~100%,12个化合物对褐飞虱的杀死率可达70%~100%.当测试浓度降为100 μg/mL时,5个化合物对蚜虫的杀灭活性可达50%~80%.

In order to find novel pyrazole oxime ethers with good bioactivities, a series of novel pyrazole oxime ether compounds containing substituted pyrazole moiety were designed and synthesized according to the method of active substructure combination. Their structures were characterized by 1H NMR,13C NMR, and elemental analysis. Preliminary bioassay displayed that most target compounds had good insecticidal activities. At the concentration of 500 μg/mL, sixteen compounds showed insecticidal activity against Oriental armyworm with 80%~100%, fourteen compounds exhibited insecticidal activity against Aphis medicaginis with 80%~100%, and twelve compounds showed insecticidal activity against Nilaparvata lugens with 70%~100%. When the dosage was lowered to 100 μg/mL, five compounds still possessed inhibitory effect against Aphis medicaginis with 50%~80%.
