Description

一种N-芳基取代内酰胺类化合物的合成方法
技术领域
本发明属于有机合成技术领域,具体涉及一种N-芳基取代内酰胺类化合物的合成方法。
背景技术
N-芳基取代内酰胺类化合物广泛存在于自然界的生物碱中,这些生物碱在治疗阿尔兹海默症以及帕金森症等方面具有显著的生物活性。目前,该类化合物的合成方法主要有:1)取代氮杂芳香类化合物的去芳构化反应;2)取代官能团化链状胺类化合物的缩合反应;3)过渡金属促进N-芳基取代饱和环胺类化合物的氧化/缩环氧化反应等。虽然这些方法可以有效地合成N-芳基取代内酰胺类化合物,但仍存在一些急需解决的问题,比如:反应步骤繁琐、原料不易制备、底物普适性差以及过渡金属催化剂/氧化剂的使用等,这些不足之处也使得上述方法的实用性受到很大限制。有鉴于此,进一步研究并开发N-芳基取代内酰胺类化合物的简捷、高效、绿色新方法具有重要的理论意义和应用价值。
发明内容
本发明解决的技术问题是提供了一种N-芳基取代内酰胺类化合物的合成方法,该合成方法通过非金属氧铵盐类化合物以及叔丁基过氧化氢促进N-芳基取代饱和环胺类化合物的多步串联反应合成N-芳基取代内酰胺类化合物,具有操作简便、无需过渡金属催化、底物适用范围广等优点,适合于工业化生产。
本发明为解决上述技术问题采用如下技术方案,一种N-芳基取代内酰胺类化合物的合成方法,其特征在于具体步骤为:将N-芳基取代饱和环胺类化合物1和氧铵盐类化合物2溶于反应溶剂中,再向反应体系加入氧化剂和添加剂,在空气气氛下于80-120℃反应制得目标产物N-芳基取代内酰胺类化合物3,该合成过程中的反应方程式为:
其中R1为苯基、取代苯基、萘基或杂芳香基,取代苯基苯环上的取代基为氟、氯、溴、碘、C1-4烷基或烷氧基、酯基、氰基、三氟甲基、硝基或苯基;X=C或N,R2为苯基、取代苯基、萘基或杂芳香基,取代苯基苯环上的取代基为氢、氟、氯、溴、碘、C1-4烷基或烷氧基、酯基、氰基、三氟甲基或硝基;T+Y-Y-为BF4 -、ClO4 -或PF6 -;反应溶剂为甲苯、乙腈或四氢呋喃;氧化剂为叔丁基过氧氢或二叔丁基过氧化物;添加剂为三氟乙酸、乙酸或三氟甲磺酸。
进一步优选,所述的N-芳基取代饱和环胺类化合物1、氧铵盐类化合物2、氧化剂和添加剂的投料物质的量之比为1:1-2:2-4:0.5-1。
本发明与现有技术相比具有以下优点:(1)本发明通过N-芳基取代饱和环胺类化合物与氧铵盐类化合物之间的多步串联反应,直接合成出N-芳基取代内酰胺类化合物,该反应直接构建出内酰胺结构单元,整个过程操作简单、效率高;(2)本发明反应原料简单易得;(3)本发明合成过程无需使用任何金属催化剂,具有经济、绿色、对环境友好的特点;(4)本发明底物的适用范围广。因此,本发明为N-芳基取代内酰胺类化合物的合成提供了一种经济实用的新方法。
