General Synthesis of Useful Chelating Reagents Having a Sugar Unit, 1,3-Diamino-2-propyl β-d-Glucopyranoside and 1,3-Diamino-2-propyl α-d-Mannopyranoside

Two 1,3-propanediamine derivatives bearing sugar units, 1,3-diamino-2-propyl ß-d-glucopyranoside (2-β-d-Glc-pn) and 1,3-diamino-2-propyl α-d-mannopyranoside (2-α-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-β-d-Glc-pn)2SO4] have been determined by X-ray crystallography.
