A visible light‐induced photocatalytic intramolecular cyclization of styryl azides has been developed in the presence of the ruthenium complex Ru(bpy)3Cl2 (0.5 mol%) as photocatalyst at room temperature. The present photocatalytic strategy features operational simplicity as well as high functional group tolerance, and provides a facile access to various 2‐substituted N‐free indoles in good to excellent
在室温下,在钌络合物Ru(bpy)3 Cl 2(0.5 mol%)作为光催化剂存在的情况下,已经开发了可见光诱导的苯乙烯叠氮化物的光催化分子内环化反应。当前的光催化策略具有操作简便以及对官能团的耐受性高的特点,并提供了以良好或优异的收率轻松获得各种2个取代的N无氮吲哚的方法。重要的是,本方法可以采用阳光作为光源以提供相应的产物而不会损失反应效率。
