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-carbon bond formation of some generality.
Buenolide阴离子不与原酸酯反应,而butenolides不与衍生自缩醛和原酸酯的碳正离子反应。然而,丁烯内酯(作为碳负离子)和烷氧基烷烃(作为稳定的碳正离子)的双重活化导致某种程度的高产率碳-碳键形成。
