Photoredox-catalyzed alkylarylation of activated alkenes via a ring-opening/Truce–Smiles rearrangement cascade

Abstract

A photoredox-catalyzed alkylarylation of activated alkenes via a radical C–C bond cleavage/Truce–Smiles rearrangement cascade is developed. The protocol features mild and redox-neutral conditions, broad substrate scope and excellent functional group compatibility, providing a facile and efficient approach to the long-chain distal keto-amides with all-carbon quaternary centers at the alpha position.
