Photoredox Catalytic Sulfonylation/Cyclization of Allyl‐Tethered Aroyl Ketene Dithioacetals Toward Sulfonated Benzoxepines
Wanqing Zhao, Anxu Pan, Bin Sheng, Cuifu Jiang, Man Zhang, Nengneng ZhouA general and efficient methodology for the synthesis of benzoxepine derivatives via visible‐light‐induced regioselective radical cyclization has been developed. This method has good regioselectivity, is operationally simple, and exhibits high‐functional group tolerance.
