2,6-Dideoxy-2,6-imino-l-glycero-d-ido-heptitol

Abstract

The title molecule, C7H15NO5, the major product from selective enzymatic oxidation followed by hydrogenolysis of the corresponding azidoheptitol, was found by X-ray crystallography to exisit in a chair conformation with three axial hydroxyl groups. One of the hydroxymethyl groups is disordered over two sets of sites in a 0.590 (3):0.410 (3) ratio. In the crystal, O—H...O, O—H...(O,O), O—H...N and N—H...O hydrogen bonding occurs.
