ResumoThe reaction of α-carbomethoxy-γ-benzylidenebutenolide with diazomethane has been studied, and the β-methylbutenolide structure of the resulting product established through degradative and synthetic work. Extension of this direct C-methylation to other related butenolides is presented. Hydrogenation of enol lactones is discussed in some detail.
