Catalytic activity of a novel water-soluble cross-linked polymer imprinted by a transition-state analogue for the stereoselective hydrolysis of enantiomeric amino acid esters.
Publication date: 1996
Abstract: A novel water-soluble cross-linked polymer catalyst containing L- histidine and quarternary trimethylammonium groups, which was imprinted by a racemic transition-state analogue of phenyl 1- benzyloxycarbonyl-3-methylpentylphosphonate for the hydrolysis of p- nitrophenyl N-(benzyloxycarbonyl)-L (or D)-leucinate (Z-L (or D)-Leu- PNP), exhibited the notable substrate stereospecificity for Z-L-Leu- PNP in the hydrolyses of enantiomeric amino acid p-nitrophenyl esters in 10 vol% DMSO (or MeCN)-Tris buffer pH 7.15) at 303 K.
