摘要

A new method to access sulfonated dibenz[b,e]azepines via visible-light photoredox catalysis is described.Employing inexpensive and commercially available sulfonyl chlorides to form the sulfonyl radicals enables the alkyne addition reaction followed by a 7-membered radical cyclization step to furnish sulfonated dibenzazepines.
