title: Gold-catalyzed [4+3]-annulation of oxabicyclic benzenes with 2-substituted allylsilanes through tandem allylation and cyclization.
abstract: This work reports new gold-catalyzed [4+3]-annulations of oxacyclic benzenes with 2-substituted allylsilanes through tandem allylation and cyclization; on the basis of experimental observations, we propose a mechanism involving the opening of the oxacyclic ring by a PPh3Au+-assisted SN2-attack of allylsilanes.
