Abstract: Polymer catalysts, cross-linked with N,N'-ethylene (C-2) {or butylene (C-4)}-bisacrylamide containing L-histidine and quaternary trimethylammonium groups were imprinted with a racemic transition-state analogue of phenyl 1- benzyloxycarbonyl-3-methylpentylphosphonate for the hydrolysis of p-ni(rophenyl N-(benzyloxycarbonyl)-L (or D)-leucinate {Z-L (Dr D)-Leu-PNP}. Maximal stereoselectivity (L/D = 8.4) was obtained by using N,N'-C-4-bisacrylamide cross-linked polymer catalyst, which was copolymerized with hydrophobic styrene monomer.
