γ-(1-Ethoxyvinyl)- and β-(1-ethoxyvinyl)-α-ethoxycarbonyl-γ-butyrolactones were obtained by the reaction of 2-(1-ethoxyvinyl)oxiranes with sodiomalonic ester.Decarboxylation of the γ-(1-ethoxyvinyl)-α-ethoxycarbonyl-γ-butyrolactones in DMSO leads to γ-(1-ethoxyvinyl)-γ-butyrolactones, the hydrolysis of which gives γ-acetyl-γ-butyrolactones.Ethyl trans-3-acetyl-3-pentenoate was obtained by decarboxylation of γ-methyl-3-(1-ethoxyvinyl)-α-ethoxycarbonyl-γ-butyrolactone in DMSO.
