  cis-Nitromethylene neonicotinoids as new nicotinic family: Synthesis, structural diversity, and insecticidal evaluation of hexahydroimidazo[1,2-α]pyridine

  摘要：

  A series of neonicotinoids analogues of hexahydroimidazo[1,2-alpha]pyridine were modified at 5-, 6-, and 7-positions, and their insecticidal activities were evaluated. Introducing a methyl or ethyl at 7-position increased the insecticidal activities, while other substituents decreased activities. When alkyl substituents were introduced to 7-position, the insecticidal activities against Pea aphids decreased in the order methyl (7a) > ethyl (7b) > n-butyl (7e) > phenyl (7f) > n-propyl (7c) > iso-propyl (7d), p-NO2-phenyl (7g). Modifications at 5-, 6- or both at 6- and 7-positions with methyl or ethyl were unfavorable to activities. Interestingly, introducing methyl to 7-position not only increased insecticidal activities against pea aphids, but also show higher insecticidal activities than imidacloprid against imidacloprid-resistant brown planthopper.

  PREPARATION METHOD AND USE OF COMPOUNDS HAVING HIGH INSECTICIDAL ACTIVITIES

  摘要：

  本发明公开了一种亚硝基甲烯衍生物，以及它们的制备方法和用途。杀虫活性测试表明，本发明的亚硝基甲烯衍生物不仅对具有刺吸型或擦伤型口器的昆虫（如蚜虫、叶蝉、植食蝗、蓟马和烟粉虱及其抗性品系）表现出高杀虫活性，而且对水稻纵卷叶象、胭脂蜘蛛螨等也表现出高杀虫活性，它们还可用于预防卫生害虫和白蚁。
