Abstract An iron(III)-BPsalan complex was found to efficiently catalyze the asymmetric chlorination reaction of cyclic β-keto esters and N-Boc oxindoles, affording the corresponding chlorinated products in high yield and up to 92% ee with NCS as chlorination reagent under mild reaction conditions. An iron(III)-BPsalan complex was found to efficiently catalyze the asymmetric chlorination reaction of
