We report for the first time the coupling of activated thioamides with alcohols to efficiently form thionoesters via a palladium-catalyzed C–N cleavage strategy. The new approach employs thioamides as a thioacylating reagent to give thionoesters in moderate to good yields. Notably, this methodology demonstrates a broad substrate scope, as alkyl/aryl alcohols are well tolerated, and this process might

Here we report a convenient synthesis of thionoesters by base-catalyzed transesterification. Benzyl and alkyl thionobenzoates and thionoheterobenzoates were efficiently prepared using various alcohols catalyzed by the corresponding sodium alkoxide. This methodology features a broad substrate scope, good to excellent yields, short reaction times, while simultaneously driving the reaction toward completion
