摘要
以 3-氨甲基吡啶和 2 -氯 - 5 -氨甲基吡啶为原料先与 2 -氰基 - 3,3-二甲硫基丙烯腈反应 ,产物不经分离再与脂肪胺反应合成了 14个未见文献报道的开环类吡虫啉结构类似物。所有目标化合物均经元素分析、1H NMR确证。初步活性测试结果表明含硫化合物的杀虫活性优于双氨基化合物 ,其中 4 c对豆蚜的抑制率最高达 87.6%。
After the reaction of 3 aminomethyl or 2 chloride 5 aminomethyl pyridine with 2 cyano 3,3 dimethylthioacrylonitrile, the simple fatty amines were added to the unseparated reactant.Fourteen novel compounds were obtained. All the structures were confirmed by elemental analysis , 1H NMR and the insecticidal activities of the compounds were evaluated.
