An efficient, mild, and metal‐free radical cascade annulation strategy for 2‐substituted‐3‐sulfenylindoles from 2‐alkynyl‐azidoarenes by vicinal thioamination of alkynes, catalyzed by a eosin Y photoredox catalyst mediated by visible light in the presence of air as mild oxidant.
一种有效的,温和的,金属自由基的级联环化策略,其通过炔烃的邻位硫代胺化反应制得的2-炔基-叠氮基芳烃中的2-取代的3-亚磺酰基吲哚,由曙红Y光氧化还原催化剂催化,可见光在空气存在下介导。温和的氧化剂。
