A domino palladium-catalyzed recombinant γ-isomerization and reverse Wacker oxidation of γ-vinyl-γ-butyrolactone has been explored. The strategy has been used in the stereoselective synthesis of (+)-trans-, (–)- and (+)-disparlures. The synthesis was achieved in seven to eight steps from D-glucono-δ-lactone with overall yields of 19.3, 20.7 and 22.6 %, respectively.
