title: 1,3-Dioxo-2,3-dihydro-1H-isoindol-2-yl 2,3,4-tri-O-acetyl-β-d-xyloside.
abstract: The title compound, C(19)H(19)NO(10), was obtained from the reaction of α-d-1-bromo-2,3,4-tri-O-acetylxylose with N-hy-droxy-phthalimide in the presence of potassium carbonate. The asymmetric unit contains two independent mol-ecules, in which the O-CH-O-N torsion angles are 73.0 (4) and 65.0 (4)°. The hexa-pyranosyl rings adopt chair conformations and the substituent groups are in equatorial positions. In the crystal, mol-ecules are linked by nonclassical C-H⋯O hydrogen bonds.
