Darzens condensation of aromatic aldehydes with ω-bromoacetophenone in aqueous chiral micelles formed from the chiral surfactants, N-dodecyl-N,N-dodecyl-N,N-dimethyl ephedrine ( I a) and N-hex-adecyl-N, N-dimethyl ephedrine bromide ( I b), afforded the corresponding epoxyketones with enan-tiomeric excess up to 11.

There have a growing demand of enantiomers in today\'s society, as the chiral surfactants have regional selective, chiral catalysis and chiral recognition ability, so the applications of chiral surfactants are receiving increasing attention in chiral synthesis, chiral recognition and chiral separation.
