Four optical isomers of γ-hydroxyglutamic acid were prepared in pure states by opticalresolution of two racemic diastereoisomers through brucine salt of N-benzyloxycarbonyl amino acid or strychnine salt of N-benzoyl derivative. Configurations of α- and γ-asymmetric carbon atoms of these isomers were estimated from contribution to molecular rotation and character of taste exhibition. These determinations

Two chiral binuclearcopper(II) complexes were synthesized and characterized for the first time as efficient chemoselective catalysts for the hydrolysis of aryl glycosides and disaccharides in aqueous solution at near neutral pH. Under these conditions, discrimination of epimeric aryl α-glycopyranosides was observed by both 29-fold different reaction rates and 3-fold different proficiency of the catalyst
