A palladium-catalyzed cascade Heck-type cyclization and carbonylation reaction has been developed for the synthesis of functionalized thioesters. With arylsulfonyl chlorides as odorless and readily available sulfur source, a variety of...

A general and straightforward strategy for the synthesis of thioester-substituted oxindoles via a palladium-catalyzed thiocarbonylative cyclization process has been developed. With sulfonyl chlorides as promising sulfur source, a wide range of thioester-substituted oxindoles were obtained in moderate to high yields. Both aryl and alkyl sulfonyl chlorides were well tolerated, and Mo(CO) 6 played a dual role as both a CO source and a reductant in this approach.
