A palladium-catalyzed conia-ene reaction of 1-alkynylindolin-3-ones has been developed. Three examples of pyrrolo[1,2-a]indoline derivatives were readily obtained with yields up to 82% utilizing this strategy. Importantly, this palladium-catalyzed intramolecular cyclization process represents an important contribution to the application of indole-3-one derivatives.
