二醛构建的具有杀虫活性的含氮或氧杂环化合物及其制备方法 技术领域
本发明涉及新型新烟碱类的杀虫剂、 及其制备方法和应用。 背景技术
以吡虫啉为代表的新烟碱类杀虫剂因杀虫活性高, 杀虫谱广,对哺乳动物和水 生动物毒性低,且有良好的系统物性及适当的田间稳定性和环境友好性, 成为新农 药创制的重要热点领域。 后来又相继开发出噻虫啉、 噻虫胺、 噻虫嗪、 啶虫脒、 烯 啶虫胺、 呋虫胺等一系列烟碱类杀虫剂 (参见欧洲专利 247477、 296453、 685477、 235725、 235725、 315826、 192060、 244777、 0386565、 580553和 1031566, 日本 专利 62292765、 8259568、 8291171和 7242633)。
