A synthesis of enantiomerically pure lactone 11a from commercially available (S)-(+)-carvone has been developed. The synthesis constitutes a formal synthesis of paeonilactone A and B and involves a stereoselective palladium-catalyzed 1,4-oxylactonization of a conjugated diene to introduce two of the oxygen substituents required for the target.
