etoxazole analogues and benzoylphenylureas, a series of 2-(2,6-difluorophenyl)-4-(4-substitutedphenyl)-1,3-oxazolines 4a–y were designed and synthesized. It was found that most of these compounds showed excellent acaricidal activities. They gave above 85% mortality at a concentration of 2.5 mg L−1, both for the eggs and larvae of spider mites. Some compounds also showed excellent insecticidal activities
基于结构-活性关系 乙恶唑设计并合成了一系列的2-(2,6-二氟苯基)-4-(4-取代的苯基)-1,3-恶唑啉4a-y和苯甲酰基苯基脲。发现大多数这些化合物显示出优异的杀螨活性。当浓度为2.5 mg L -1时,它们对蜘蛛螨的卵和幼虫的死亡率都达到85%以上。一些化合物还表现出优异的杀虫活性。2,4-二苯基-1,3-恶唑啉的4-苯基上的取代基的位置和类型对活性有很大影响。2-(2,6-二氟苯基)-4-(2-Cl-4-(4-Cl-苯氧基)苯基)-1,3-恶唑啉(4r)在2.5 mg L -1下表现出100%的杀螨作用,对甜菜夜蛾和小菜蛾的死亡率分别为12.5 mg L -1和65%和93%,几乎与乙恶唑。新发现的结构-活性关系也可能有益于进一步的杀螨剂/杀虫剂开发。
