Disclosed is an alanine racemase chiral binaphthol derivative having the ability to recognize amino alcohols selectively on the basis of chirality and transform amino acids from an L-form into a D-form. Methods for the optical resolution of amino acid or amino alcohol and for the optical transformation of D- and L-forms of amino acids using the binaphthol derivative are also provided.

(R)-Amino alcohol with an enantiomeric excess of >95% was resolved by reactive extraction processes from 2 equiv of racemic alcohol using a chiral receptor 2 as an enantioselective extractant. One resolution cycle is composed of three extractions: a stereoselective reversible imine formation, a stereoselective irreversible imine hydrolysis, and the recovery of 2 and enantiomeric amino alcohols.
