title: Potentiometric and spectroscopic study of copper (II) ion binding by 1,6-anhydro-derivatives of aminosugars.
abstract: Potentiometric and spectroscopic studies of complexes of Cu2+ with two 1,6-anhydro derivatives of aminosugars, 1,6-anhydro-2-deoxy-2N-methylamino-beta-D-mannopyranose and 1,6-anhydro-3,4-epimino-beta-D-altropyranose, showed that the epimino nitrogen donor binds Cu(II) ions, but its position prevents formation of stable chelate complexes. The other ligand is very effective in metal ion coordination, but contrary to the homologous glucosamine derivative, it does not form any dimeric species.
