One-pot syntheses of 2,3-dihydrothiopyran-4-one derivatives by Pd/Cu-catalyzed reactions of alpha,beta-unsaturated thioesters with propargyl alcohols.
2,3-Dihydrothiopyran-4-one derivatives were readily prepared by Pd/Cu-catalyzed reactions between alpha,beta-unsaturated thioesters and propargyl alcohols in the presence of bases. Of note, both carbon-sulfur bonds were cleaved as a result of the single procedure.
