Abstract

Abstract Asymmetric resins chelating copper(II) ions to L-proline or L-hydroxyproline ligands fixed in macroporous methacrylate copolymers were synthesized. The sorbents were used for the ligand-exchange chromatography of amino acid racemates and showed high enantioselectivity by retaining preferentially the L-isomers of the amino acids tested (except proline).
