以氯虫苯甲酰胺作为先导化合物, 2-氰基吡啶作为起始原料, 经加成、环合、取代、水解、氯化和胺解反应, 设计合成了30个新型的吡啶联噻唑双酰胺类化合物, 其结构经1H NMR、13C NMR和高分辨质谱进行表征. 初步杀虫活性测试结果显示, 在浓度为500 mg/L条件下, IX7IX12IX20以及IX26对粘虫(Mythimna separata)的杀虫活性为100%, 另外, IX20在500 mg/L时对草地贪夜蛾(Spodoptera frugiperda)的杀虫活性也为100%. 当浓度为200 mg/L时,IX20对粘虫的杀虫活性为50%.

Based on the chlorantraniliprole as leading compound, thirty novel pyridyl thiazole diamide compounds using 2-cyanopyridine as the starting material were synthesized through addition, cyclization, substitution, hydrolysis, chlorination, and ammonolysis reactions. The structures of title compounds were characterized by 1H NMR, 13C NMR and HRMS. The bioassay results indicated that at 500 mg/L, compounds IX7, IX12, IX20 and IX26 exhibited 100% insecticidal activities against Mythimna separata, and compound IX20 exhibited 100% insecticidal activity against Spodoptera frugiperda. When the concentration was at 200 mg/L, IX20 exhibited 50% insecticidal activity against Mythimna separata.

Key words: thiazole, diamide, pyridine, insecticidal activity
