A series of novel phenylurea derivatives were designed and synthesized according to the method of active groups linkage and the principle of aromatic groups bioisosterism in this study. The structures of the novel phenylurea derivatives were confirmed based on ESI-MS, IR and 1H-NMR spectral data. All of the compounds were evaluated for the insecticidal activity against the third instars larvae of Spodoptera exigua Hiibner, Plutella xyllostella Linnaeus, Helicoverpa armigera Hubner and Pieris rapae Linne respectively, at the concentration of 10 mg/L. The results showed that all of the derivatives displayed strong insecticidal activity. Most of the compounds presented higher insecticidal activity against S. exigua than the reference compounds tebufenozide, chlorbenzuron and metaflumizone. Among the synthesized compounds, 3b, 3d, 3f, 4b and 4g displayed broad spectrum insecticidal activity.
本研究根据活性基团联接法和芳香基团生物等排原则设计并合成了一系列新型苯脲衍生物。通过ESI-MS、IR和1H-NMR光谱数据确证了新型苯脲衍生物的结构。所有化合物在10 mg/L浓度下分别对甜菜夜蛾、小菜蛾、棉铃虫和菜青虫的3龄幼虫进行了杀虫活性评价。结果显示,所有衍生物均显示出较强的杀虫活性。大多数化合物对甜菜夜蛾的杀虫活性高于参考化合物虫酰肼、灭幼脲和氟苯脲。在合成的化合物中,3b、3d、3f、4b和4g显示出广谱杀虫活性。
