2,3,4,6-Tetra-O-acetyl-2-phthalimido-?-d-glucopyran-oside.

ABSTRACT: In the crystal structure of the title compound, C(24)H(27)NO(11), a substituted tetra-acetyl glucopyran-oside derivative, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into ribbons propagated in [010]. The d configuration has been attributed on the basis of the synthesis and the ? anomer has been determined from the structure.

Project description:THE TITLE COMPOUND [SYSTEMATIC NAME: (2R,3R,4S,5R,6R)-2-(acet-oxy-meth-yl)-6-propoxytetra-hydro-2H-pyran-3,4,5-triyl triacetate], C(17)H(26)O(10), was formed by a Koenigs-Knorr reaction of 2,3,4,6-tetra-O-acetyl-?-d-glucopyranosyl bromide and n-propanol. The central ring adopts a chair conformation. The crystal does not contain any significant inter-actions such as hydrogen bonds.

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.

Project description:The crystal structure of the title compound, C(28)H(38)O(11), solved and refined against synchrotron diffraction data, contains two formula units in the asymmetric unit. In both mol-ecules, the dihydro-pyran ring along with its methyl substituents is disordered and adopts two alternative half-chair conformations. The occupancy of the major conformers of the two mol-ecules refined to 0.858 (5) and 0.523 (5).

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.
