Preparation of α- and β-d-glucoseptanose pentaacetates

The α- and β-d-glucoseptanose pentaacetates have been prepared by treatment of ethyl 1-thio-β-d-glucoseptanoside tetraacetate with mercury(II) acetate in acetic acid. The solid state structure of the β-isomer has been determined by X-ray diffraction.
