Isoxazoline derivatives are new insecticides discovered in the 21st century. Because of their unique insecticidal mechanism, high selectivity, safety, and no significant cross resistance with the existing pesticides on the market, they have become a hot spot in the field of pesticide research. Herein, a series of novel isoxazoline derivatives containing ether and oxime-ether structures were designed and synthesized
现有的农用杀虫剂因长期使用产生了耐药性。异恶唑啉衍生物是21世纪发现的新型杀虫剂。由于其独特的杀虫机理、高选择性、安全性,与市场上现有农药无明显交叉抗性,成为农药研究领域的热点。在此,以农药氟拉烷为模板结构,通过支架跳跃策略设计合成了一系列含有醚和肟-醚结构的新型异恶唑啉衍生物。通过对杀虫活性和系统构效关系的考察,发现了一系列具有较高杀虫活性的化合物,化合物I-4、II-9和II-13对小菜蛾的 LC 50值为 0.00008–0.00036 mg/L,成为新型杀虫剂候选物。这些化合物还表现出对 14 种植物真菌的广谱杀真菌活性。目前的工作为基于支架跳跃策略设计新型异恶唑啉化合物提供了参考。
