A simple and tandem synthetic approach, which offers an efficient, direct route to highly substituted indenes, has been developed by palladium- or nickel-catalyzed cyclization of propargylic compounds and nitrogen nucleophiles. The reaction takes place under mild conditions, and a possible mechansim is proposed.
