Abstract

The synthesis of 2-amino-1,6-anhydro-2-deoxy-4- O-methyl-β- d-mannopyranose ( 3) is described. Potentiometric and spectroscopic methods were used to evaluate the equilibria and the complex structures in systems containing Cu(II) ions and 3, and two other 1,6-anhydro derivatives. The results showed that no mannosamine derivative is able to form dimeric species found earlier for 1,6-anhydro-glucosamine ligands. The correlation between complex formation and sugar structure is discussed.
