Epoxides : Part II - Synthesis of Butyrolactones

1,1-Diarylethylene oxides (Ia-c) react with diethyl malonate in the presence of sodium ethoxide to give γ,γ-diaryl-α-ethoxycarbonyl-γ-butyrolactones (IIa-c) which yield the carboxylactones (IIIa-c) upon alkaline hydrolysis.Decarboxylation of IIIa-c furnishes the corresponding γ,γ-diaryl-γ-butyrolactones (IVa-c).
