title: 3,4-Dicyano-phenyl 2,3,4,6-tetra-O-acetyl-α-d-glucopyran-oside.
abstract: The title compound, C(22)H(22)N(2)O(10), was prepared by the glycosidation method through nitrite displacement on substituted nitro-phthalonitrile. The mol-ecule contains a benzene ring, two nitrile groups and an acetyl-protected d-glucose fragment which adopts a chair conformation. The absolute configuration was determined by the use of d-glucose as starting material. All substituents of the protected sugar are in equatorial positions, with the exclusive presence of the α-anomer. The crystal packing is stabilized by C-H⋯O and C-H⋯N hydrogen-bonding inter-actions.
