Abstract
The results of a systematic study are summarized on chromatographic resolutions of racemic amino acids using ligand exchange on copper(II) ion-charged polystyrene type resins containing residues of optically active proline (I), hydroxyproline (II), allo-hydroxy-proline (III) and azetidine carboxylic acid (IV). Possible variants of the enantioselective complex formation in the resine phase are discussed.
Several examples of quantitative resolutions of racemic amino acids as well as members of other classes of chelating organic compounds are given.
