β-烯胺酯为关键中间体的串联反应研究进展

Development of Domino Reactions with β-Enamino Esters as Key Intermediates

串联反应具有原料简单易得、中间产物无需分离提纯、操作简单、节省溶剂和降低消耗等很多独特优点,已成为当前有机合成研究的热点课题.缺电子炔烃与芳香胺在温和条件下快速反应生成的β-烯胺酯,具有丰富的化学反应性质,可以作为多组分串联反应的关键中间体,和其它组分进行串联反应,构建结构复杂的碳链、碳环、杂环化合物和螺环化合物.综述了近年来此类直接生成的β-烯胺酯参与的多组分串联反应的最新研究进展.

Domino reactions have attracted much high attention in recent years due to its convergence, productivity, facile execution and generation of highly diverse and complex products from easily available starting materials in a single operation. Addition of primary amines to electron-deficient alkynes could generated reactive enaminone （ester） in mild conditions, which have shown versatile reactivity and have been widely used in domino procedure as key reactive intermediate to develop a number of carbon-carbon bond formation reactions, heterocyclic and spiro cyclic constructions. In this paper the recent devel- opments of the domino reactions with enamino esters as key intermediates based on our experimental investigation are re- viewed.
