Eight 2-(5-(trifluoromethyl)pyridyloxymethyl)-1,3,4-oxadiazoles have been designed and synthesized by four-step synthetic route. The structures of all new compounds were confirmed by NMR, mass and HR mass spectroscopy. The preliminary bioassay tests show that some compounds, especially those having fluorine on the benzene ring (II4 and II5), exhibited a significant insecticidal activity on armyworm
通过四步合成路线设计并合成了八种2-(5-(三氟甲基)吡啶基氧基甲基)-1,3,4-恶二唑。所有新化合物的结构均通过NMR,质谱和HR质谱确认。初步的生物测定测试表明,某些化合物,尤其是那些在苯环上具有氟的化合物(II 4和II 5),对粘虫Leucania separata Walker的杀虫活性为500 mg l -1。
