可见光诱导的1,n-烯炔的自由基串联环化反应研究进展

Progress in the Visible-Light-Induced Radical Cascade Cyclization of 1,n-Enynes

碳氮杂环化合物广泛存在于天然产物、生物活性分子、药物等相关化合物以及许多其他精细化学品中。近年来,发展了大量的合成方法制备该类化合物。其中,可见光诱导的1,n-烯炔的自由基串联环化反应条件绿色友好、操作简单、化学选择性和官能团兼容性好,已成为制备该类化合物的强有力工具。本文主要根据自由基产生的类型概述了近来可见光诱导的1,n-烯炔的自由基串联环化反应这一快速发展领域的新进展。

Carbon and nitrogen heterocyclic compounds are widely found in natural products,bioactive molecules,drugs and many other fine chemicals.In recent years,a large number of synthetic methods have been developed to prepare these compounds.Among them,visible-light-induced radical cascade cyclization of 1,n-enynes has become a powerful tool for the preparation of these compounds because of its green and friendly conditions,simple operation,good chemical selectivity and functional group compatibility.Based on the types of free radicals,this paper summarizes the latest progress in the field of visible light induced radical cascade cyclization of 1,n-enynes since 2013.
