Piperidine and pyrrolidine derivatives are important nitrogen heterocyclic structures with a wide range of biological activities. However, reported methods for their construction often face problems of requiring the use of expensive metal catalysts, highly toxic reaction reagents or hazardous reaction conditions. Herein, an efficient route from halogenated amides to piperidines and pyrrolidines was disclosed
哌啶和吡咯烷衍生物是重要的氮杂环结构,具有广泛的生物活性。然而,已报道的构建它们的方法经常面临需要使用昂贵的金属催化剂、剧毒反应试剂或危险反应条件的问题。本文公开了一种从卤代酰胺到哌啶和吡咯烷的有效途径。在该方法中,酰胺活化、腈离子还原和分子内亲核取代被整合到一锅反应中。反应条件温和,不使用金属催化剂。多种N-取代和部分C-取代哌啶和吡咯烷的合成变得方便,并获得了良好的收率。
