摘　　要：报道了一种基于原位捕获胺的Ugi四组分反应及其后修饰串联环化反应策略,制备了三类六元和七元含氮杂环化合物.根据该串联反应策略,胺原位生成,并立即被捕获参与Ugi四组分反应和随后的修饰串联反应.从廉价易得的硝基化合物出发,扩大了底物的适用范围,并解决了胺易氧化、稳定性和通用性差的问题.该串联反应策略具有良好的原子经济性和通用性,是制备含氮杂环化合物的一种新方法.通过一系列条件控制实验,提出了反应机理.The tandem reaction strategy of Ugi four-component reaction and its subsequent modification reaction based on in situ capture of amines to prepare three types of six-and seven-membered nitrogen-heterocycles are reported.According to this strategy,amines were synthesized in situ and immediately worked as the substrate for the Ugi four-component reaction reaction and subsequent modification tandem reaction.Starting from cheap and easily available nitro compounds,the application scope of substrates has been expanded and the problems of amines of easy oxidation,poor stability and versatility have been solved.Furthermore,due to the atom economy and versatility,the tandem reaction strategy has become a new approach for the synthesis of nitrogen-hete-rocycles.In addition,based on a series of conditional control experiments,a plausible mechanism for the reaction is proposed.
