A simple and practical method for the construction of 1,3,5-trisubstituted imidazolidine derivatives via [3 + 2] cycloaddition reaction has been developed. This reaction could smoothly proceed between nonstabilized azomethine ylides generated in situ and 2-benzothiazolamines to deliver a wide scope of differently substituted imidazolidines in high yields (up to 98%). The structure of one example was
开发了一种通过[3+2]环加成反应构建1,3,5-三取代咪唑烷衍生物的简单实用方法。该反应可以在原位产生的不稳定的偶氮甲碱叶立德和 2-苯并噻唑胺之间顺利进行,从而以高产率(高达 98%)提供范围广泛的不同取代的咪唑烷。通过X射线单晶结构分析确认了一个实施例的结构。
