class of popular insecticide because of its unique mode of action. In order to find more new RyRs activators as insecticidal agents, a series of 18 novel chiral anthranilic diamides were designed by introducing the d -alanine acid and d -serine acid esters as well as trifluoroethoxyl group into the anthranilic diamide skeleton and synthesized successfully based on anthranilic diamide and FKI-1033 structures
摘要Ryanodine受体(RyRs)激活剂因其独特的作用方式而成为一类流行的杀虫剂。为了找到更多的新型RyRs杀虫剂,通过将d-丙氨酸和d-丝氨酸酸酯以及三氟乙氧基引入到邻氨基苯甲酰胺骨架中,设计了18种新型手性邻氨基苯甲酰胺。邻氨基苯甲酰胺和FKI-1033结构。标题化合物Ia–i和IIa–i的结构已通过熔点,1H NMR,13C NMR,元素分析和比旋光分析确定。初步的生物测定结果表明,大多数标题化合物在10 mg / L(尤其是Ib)下对东方粘虫表现出相当大的杀幼虫活性。Ie和IIh在0.5 mg / L时表现出显着的杀虫活性。在0.0001 mg / L下,Ia和IId对小菜蛾的杀幼虫活性分别为80%和90%,这与氯虫腈相似。分析了结构与杀虫活性之间的关系,以揭示标题化合物骨架结构中的手性氨基酸酯,卤素原子或氰基以及三氟乙氧基的可能的共调节作用,这将为指导应用提供指导。设计和发现新的RyRs活化剂和杀虫农用化学品。
