Summary: | The title compound, C19H19NO10, was obtained from the reaction of α-d-1-bromo-2,3,4-tri-O-acetylxylose with N-hydroxyphthalimide in the presence of potassium carbonate. The asymmetric unit contains two independent molecules, in which the O—CH—O—N torsion angles are 73.0 (4) and 65.0 (4)°. The hexapyranosyl rings adopt chair conformations and the substituent groups are in equatorial positions. In the crystal, molecules are linked by nonclassical C—H...O hydrogen bonds. |
