Chiral Selectivity in the Basic or Acid a-amino Acids Homomeric
Cu(II) Complexes Range

Abstract:

Plan-tetragonal coordination in copper (II) complexes of basic and acid a-amino acids generates diastereomers having structures and solubility influenced by the nature and charge of the counter-ions, which can complex intra or inter-molecular with charged functional groups belonging to lateral catena of the ligands. Stereochemical selectivity correlates with the charge and solubility correlates with the capacity to achieve hydrogen bonds. The complexes structures depend on the chirality of the ligands involved in coordination. On this basis, is possible the chiral separation by selective crystallization of the hetero-chiral diastereomers from the homo-chiral one. Keywords: amino acid copper complex, chiral diastereomers, anion complexation, chiral separation
