ABSTRACT:
Chiral, hinged, asymmetric host binaphthyl-based multiheteromacrocycles of oxygen covalently bonded to styrene/divinylbenzene copolymers are provided. These new compounds have specific chiral recognition properties, which properties make these new compounds useful for separating or resolving racemic and other mixtures of amino acids, amino acid esters and salts thereof for either or both of analytical purposes or large scale manufacturing procedures.
