title: Highly regioselective synthesis of 2,3-disubstituted indenes via a novel palladium-catalyzed cyclization reaction of propargylic carbonates with carbon nucleophiles.
abstract: Palladium-catalyzed reaction of propargylic carbonates with carbon nucleophiles offers an efficient, direct route to highly substituted indenes. The reaction conditions and the scope of the process are examined, and a possible mechanism is proposed. [reaction: see text]
