by the single‐crystal X‐ray analysis, which exhibits a half‐chair conformation and dihedral angle is 49.70°. The preliminary bioassay tests showed that all the title compounds exhibited good insecticide activities against Nilaparvata legen (N. legen).
合成了八个新的新烟碱类似物1-(2-四氢糠基)-5-取代的-1,3,5-六氢三嗪-2- N-亚硝基亚胺3a - 3h,并通过1 H NMR,IR和元素分析对其结构进行了表征。3a的立体结构是通过单晶X射线分析确定的,呈现出半椅构型,二面角为49.70°。初步的生物分析测试表明,所有标题化合物均对尼拉帕拉塔(Nilaparvata legen)(N. legen)表现出良好的杀虫活性。
