Description

一种含2-苯胺基-3-氨烷基喹唑啉-4(3H)-酮结构的氮杂环化 合物
技术领域
本发明涉及一类含2-芳胺基-3-氨烷基喹唑啉-4(3H)-酮结构的氮杂环化合物及其制备和作为农用杀菌剂的应用。
背景技术
植物病害是严重危害农业生产的自然灾害之一。作为一种重要而高效的防治策略,杀菌剂被广泛应用于植物病害防治。然而,随着抗性、残留等问题的日趋严重以及人们环保意识的日益增强,传统杀菌剂面临着巨大的选择压力。喹唑啉酮是许多天然产物的结构单元,其衍生物大多具有广泛而良好的生物学活性,且毒性低、选择性高、易降解,因此,以喹唑啉酮作为母体结构创制绿色杀菌剂具有重要意义。
CN104211649公开了一类4-苯胺喹唑啉药物A及其关键中间体喹唑啉 -4(3H)-酮的制备方法及其应用。
CN101899010公开了系列具抑制人精子顶体酶活性的喹唑啉-4(3H)-酮化合物B。
发明内容
本发明的目的是提供一种新型2-芳胺基-3-氨烷基喹唑啉-4(3H)-酮结构的氮杂环化合物及其制备和作为农用杀菌剂的应用。这类化合物与已知的喹唑啉 -4(3H)-酮化合物不同,对农作物病害具有明显的抑制作用。
本发明涉及的一类含2-芳胺基-3-氨烷基喹唑啉-4(3H)-酮结构的氮杂环化合物,具有如下通式(I)所示结构特征:
式中,R1、R2、R3、R4代表氢原子、卤素原子、低级烷基或烷氧基,Ar代表苯基或取代苯基、吡啶基或取代吡啶基,n为2~5的整数。
所述2-芳胺基-3-氨烷基喹唑啉-4(3H)-酮类化合物I可以通过如下方法制备:首先,取代2-邻氨基苯甲酸经重氮化、叠氮化反应得到中间体2-叠氮基苯甲酸,该中间体经酯化反应得到2-叠氮基苯甲酸乙酯,其后经aza-Wittig等反应得到关键中间体膦亚胺以及相应的碳二亚胺,最后与二胺作用即得目标产物。
本发明通式I的化合物对植物病害(特别是番茄根腐病和水稻纹枯病以及水稻基腐病等)具有明显的抑制作用。该化合物可以直接施用,也可以加工成相应的制剂施用,也可以与那些已知的现有杀菌剂混配施用。
具体实施方式
下面结合具体实施例来进一步阐述本发明。
