Abstract

-sulfonamidobenzaldehydes is reported, affording polyfunctionalized quinolines in moderate to high yields with a broad substrate scope. A plausible reaction mechanism is proposed, highlighting the potential of yne-enones to serve as versatile synthons for the development of new annulation strategies under phosphine catalysis.
