title: One-step synthesis of alpha-pyrones from acyl chlorides by the Stille reaction.
abstract: Palladium-catalyzed stereoselective annulation of a functional vinylstannane by acyl chlorides gives the corresponding alpha-pyran-2-ones in good yields. This annulation most probably proceeds through a Stille reaction/cyclization sequence.
