A series of novel pyrimidinamine derivatives containing phenyloxazole moiety were designed and synthesized, and their structures were characterized by 1H NMR, MS, and elemental analyses. The bioassay results displayed that some compounds exhibited remarkable insecticidal activities against Aphis fabae and Tetranychus cinnabarinus. Especially, 5-chloro-6-ethyl-2-methyl-N-((2-(p-tolyl)oxazol-4-yl)me
设计并合成了一系列含有苯基恶唑部分的新型嘧啶胺衍生物,并通过1 H NMR,MS和元素分析对其结构进行了表征。生物分析结果表明,某些化合物对蚜虫和朱砂叶螨具有显着的杀虫活性。特别是,5-氯-6-乙基-2-甲基- ñ - ((2-(p -甲苯基)恶唑-4-基)甲基)嘧啶-4-胺(90)显示针对有效的活性A.蚜,优异的与商业杀虫剂吡虫啉相比。另外,5-氯-6-乙基-2-甲基-N-(((2-(4-(三氟甲基)苯基)恶唑-4-基)甲基)嘧啶-4-胺(9r)显示出对朱砂毛虫的强效活性,其效果不如市售杀虫剂螺旋螺。还讨论了目标化合物的构效关系研究。
