Abstract

An expedient protocol for the synthesis of 5-aryl-2,3-dihydropyrroles, starting from N-tosyl-protected 2-methylprop-2-en-1-amine, alkynyl bromides, and arylboronic acids, is described. The sequential reaction sequence involves nucleophilic addition of the sulfonamide to the alkynyl bromide, followed by a palladium-catalyzed tandem intramolecular Heck and intermolecular Suzuki cross-coupling reaction of the bromoalkene adduct.
