to good yields with good stereoselectivitiesvia the sequential nucleophilic ring-opening reaction of cyclopropane by H2O, aldol type reaction and subsequent cyclic transesterification mediated by the Lewis acid. The mechanism was further confirmed by introducing a substituent at the other α-position of the cyclopropyl alkyl ketone to produce two or three other products without the formation of spiro-γ-lactone
