A study of the intramolecular stille cross coupling reaction of vinylstannyl chloroformates: application to the synthesis of α-methylene lactones
Abstract
An intramolecular Stille cross coupling of vinylstannyl chloroformates catalysed by trans-benzylchlorobis(triphenylphosphine)palladium(II) has been investigated and shown to be useful for the preparation of α-methylene lactones. A novel method for the chloroformylation of alcohols in the presence of vinylstannanes is also described.
