General Synthesis of Useful Chelating Reagents Having a Sugar Unit, 1,3-Diamino-2-propyl (beta)-DGlucopyranoside and 1,3-Diamino-2-propyl (alpha)-D-Mannopyranoside

Two 1,3-propanediamine derivatives bearing sugar units, 1,3-diamino-2-propyl (beta)-D-glucopyranoside (2-(beta)-D-Glc-pn) and 1,3-diamino-2-propyl (alpha)-D-mannopyranoside (2-(alpha)-D-Man-pn), have been prepared and characterized. The structures of two peracetylated diazides, as well as a nickel complex of glucose-type ligand, [Ni(2-(beta)-D-Glc-pn)2SO4] have been determined by X-ray crystallography.
