title: Phosphine-initiated domino reaction: a convenient method for the preparation of spirocyclopentanones.
abstract: An efficient synthetic approach has been developed for the construction of the spirocyclopentanone skeleton via a phosphine-catalyzed [3+2] annulation reaction. With this novel and economical protocol, various quaternary carbon-centered spirocyclopentanones could be readily obtained.
