Synthesis of β-Alkyl-α-methylene-γ-butyrolactonesThe ylene 1 reacts with aldehydes to give 3-alkylidenesuccinic acid monoethyl esters 2, which form β-alkylidene-γ-butyrolactones 3 when treated with sodium diethyldihydroaluminate. Hydrogenation of the double bond leads to the β-alkyl-γ-butyrolactones 4. The β-alkyl-α-methylene-γ-butyrolactones 5 are obtained by Mannich reaction.
