Generation of Indeno[1,2-<i>c</i>]pyrroles via a Pd-Catalyzed Reaction of 2-Alkynylbromobenzene with Propargylic Sulfonamide

A novel route for the efficient assembly of indeno[1,2-<i>c</i>]pyrrole derivatives via a palladium-catalyzed tandem reaction of 2-alkynylbromobenzene with propargylic sulfonamide is reported. The starting materials are easily available, and the reaction proceeds smoothly with good functional group tolerance
