of enantiomeric substrates is examined using optically active dipeptide derivatives containing histidine residue in the presence of CTABr micelles. A very high stereoselectivity, kc(L)/kc(D), of 12.2 is observed in the reaction with the enantiomers of p-nitrophenyl N-methoxycarbonylphenylalanate (MocPheONp) and N-(benzyloxycarbonyl-L-leucyl)-L-histidine (ZLeuHis).
