A new type of chiral oxidants are developed and successfully applied in the asymmetric -hydroxylation of enals under the catalysis of an inexpensive achiral NHC catalyst. This type of chiral oxidants can be easily prepared from the low-cost starting materials of substituted benzoic acids and chiral prolinols through simple dehydrative amidation reactions
