A method for the regioselectivesynthesis of highlysubstitutedenolestersfromketoketenedimersβ-lactones is described. Methylphenylketene dimer was subjected to a sequential one-pot reaction sequence involving ring-opening with an organolithium to give an enolate intermediate, followed by enolate acylation with an acyl chloride to give a highlysubstitutedenolester as the final product.
