摘要
为了开发新的杀虫化合物,以氯虫苯甲酰胺为先导,通过引入氨基酸片段合成了12个新化合物,通过^(1)H NMR,^(13)C NMR和HRMS等手段进行结构表征。室内杀虫活性初步测试结果表明:在500 mg/L测试质量浓度下,多数目标化合物对黏虫(Oriental armyworm)有着较高的杀虫活性,其中化合物b在20,4 mg/L质量浓度下对黏虫分别有90%和80%的杀虫活性,化合物f在20,4 mg/L质量浓度下对黏虫分别有80%和70%的杀虫活性。
In order to find and develop new insecticidal compounds,12 compounds were designed and synthesized by introducing amino acids into the lead compound chlorantraniliprole.Their structures were characterized by ^(1)H NMR,^(13)C NMR and HRMS.The bioactivity test results showed that most of the title compounds showed good insecticidal activity against oriental armyworm.Compound b showed 90%and 80%insecticidal activity against armyworm at 20,4 mg/L,respectively,and compound f showed 80%and 70%insecticidal activity against armyworm at 20,4 mg/L,respectively.
