In the stereoselective deacylation of H–[CH2]n-1–CONHCH(CH2Ph)CO2–C6H4NO2-p (n=10 and 16), the bilayer catalytic systems of palmitoyl-l-histidine and double-chain surfactants ([CmH2m+1]2N[CH3]2Br; m=12 and 14) offered the relatively higher enantiomer rate ratios (kcatL⁄kcatD=3.7–5.6) as compared with those (kcatL⁄kcatD=3.5–3.6) obtanined with the comicellar system of palmitoyl-l-histidine and octadecyltrimethylammonium chloride.
