The synthesis of enantiomeric γ-(acyloxy)carboxylic acids and γ-lactones from racemic γ-lactones is reported, which involves lipase-catalyzed acylation of γ-hydroxycarboxylic acid sodium salts in organic solvent followed by relactonization of the unreacted enantiomer. The products were separated by extraction, no column chromatography is needed.
