A one-pot synthesis of 2-aryl- and 2-vinylindoles based on a ruthenium-catalyzed hydroamination and a palladium-catalyzed intramolecular Heck reaction is reported. The ruthenium-catalyzed addition reaction was applied to terminal as well as internal alkynes. Intramolecular Heck reactions of the resulting 2-chloroanilino enamines were achieved using an in situ generated palladium complex derived from an N-heterocyclic carbene.
