Speedy access to biarylsfused to seven-memberedsultams was achieved by starting from readily accessible N-alkylbenzenesulfonamides and 2-bromobenzylbromides. The protocol features a domino reaction and proceeds through an N-benzylation followed by an intramolecular direct C–H arylation that occurs ortho to the sulfonamide group.
