Photoredox radical Truce–Smiles rearrangement of N-sulfinyl acrylamides with sulfoxonium ylides†

The visible light-induced Truce–Smiles rearrangement reaction of N-sulfinyl acrylamides with sulfoxonium ylides is herein reported. The reaction is performed under mild conditions by radical addition/aryl migration, allowing the synthesis of a range of valuable α-arylamides in moderate to good yields. The resultant α-aryl-γ-benzoylamides were converted by late-stage modification to a number of synthetically valuable derivatives.
