含七氟异丙基的3-酰氨基苯甲酰胺类化合物的合成及杀虫活性

Synthesis and insecticidal evaluation of novel 3-acylaminobenzamides containing heptafluoroisopropyl group

摘要: 设计合成了一系列新颖的含七氟异丙基的3-酰氨基苯甲酰胺类化合物,其结构均经核磁共振氢谱、质谱和高分辨质谱确证。初步生物活性测试结果表明,在20 mg/L下,部分化合物对小菜蛾Plutella xylostella具有较高的杀虫活性,其中 8j 在4 mg/L下对小菜蛾的致死率达100%。

Abstract: A series of novel 3-acylaminobenzamides containing heptafluoroisopropyl group were synthesized,and their structures were characterized by 1H NMR,ESI-MS and HRMS.Their insecticidal activity indicated that some of the title compounds exhibited moderate to high insecticidal activity against diamondback moth(Plutella xylostella) at 20 mg/L,while compound(8j) showed mortality rate of 100% at the concentration of 4 mg/L.
