Abstract: Chalkones were asymmetrically epoxidized by H2O2 to their corresponding chiral α,β-epoxy ketones in aqueous chiral micelles formed from the chiral surfactants, N-dodecyl-N, N-dimethyl ephedrine bromides (1a) and N-hexadecyl-N,N-dimethyl ephedrine bromide (1b).The enantiomer excesses ranged from 5% to 8%.

Key words: Chiral surfactants, Epoxidation, Enantiomer, Chalkones
