Abstract
A four-step one-pot procedure involving generation of α-bromo aluminum acetals, their subsequent radical cyclization followed by oxidation of the resulting cyclic aluminum acetals and base promoted double bond migration is developed to convert α-bromoesters derived from propargylic alcohols to butenolides.
