A novel gold-catalyzed tandem cyclization/[1,2]-alkyl migration process of epoxy alkynes to spiropyranones has been discovered. From this process, the construction of adjacent multiple stereocenters with a new quaternary carbon atom is achieved. The gold-catalyzeddominoprocess is stereospecific with respect to the migrating carbon atom. A type of unusual C-C bond cleavage of epoxide systems has also
