CARBON-CARBON BOND FORMATION BY 'DOUBLE ACTIVATION'. THE SYNTHESIS OF PIPEROLIDE AND FADYENOLIDE INTERMEDIATES.

Butenolide 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
