WebHerein, we describe an effective strategy for enantioselective synthesis of oxindoles having C3-quaternary stereocenter via N-heterocyclic carbene (NHC) catalyzed desymmetrization of diol. The process is based on the catalytic asymmetric transfer acylation of primary alcohol using readily available aldehyde
