Buenolide anions do not react with orthoesters and butenolides do not react with carbocations derived from acetals and orthoesters. However double activation of the butenolide (as the carbanion) and the alkoxyalkanes (as the stabilised carbocations) leads to high yield carbon-carbonbondformation of some generality.
