4-Formyl-phenyl 2,3,4,6-tetra-O-acetyl-?-d-glucopyran-oside.

ABSTRACT: The pyran-oside ring in the title compound, C(21)H(24)O(11), has a chair conformation with the substituted benzene ring occupying an equatorial position. The crystal packing is dominated by C-H?O inter-actions that lead to the formation of supra-molecular layers in the ab plane.

3,4-Dicyano-phenyl 2,3,4,6-tetra-O-acetyl-?-d-glucopyran-oside.

Project description: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 ?-anomer. The crystal packing is stabilized by C-H?O and C-H?N hydrogen-bonding inter-actions.

4-Methoxy-phenyl 2,3,4,6-tetra-O-acetyl-1-thio-?-d-mannopyran-oside.

Project description:The title compound, C(21)H(26)O(10)S, was synthesized in a single step from mannose penta-acetate. The mol-ecular structure confirms the ? configuration of the anomeric thioaryl substituent. Spectroscopic and melting-point data obtained for the title compound are in disagreement with those previously reported, indicating the previously reported synthesis [Durette & Shen (1980 ?). Carbohydr. Res. 81, 261-274] to be erroneous. The crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds.
