2-Acetyl-amino-1,3,4,6-tetra-O-(tri-methyl-silyl)-2-de-oxy-?-d-gluco-pyran-ose.

ABSTRACT: The title compound, C20H47NO6Si4, was synthesized by per-O-tri-methyl-silylation of N-acetyl-d-glucosa-mine using chloro-tri-methyl-silane in the presence of hexa-methyl-disiloxane. The tri-methyl-silyl group and acetamido group are located on the same side of the pyran ring, showing an ?-configuration glycoside. One of the tri-methyl-silyl groups is disordered over two orientations, with site-occupancy factors of 0.625?(9) and 0.375?(9). In the crystal, N-H?O hydrogen bonds link the mol-ecules into supra-molecular chains along the a-axis direction.

The title compound, C20H47NO6Si4, was synthesized by per-O-tri-methyl-silylation of N-acetyl-d-glucosa-mine using chloro-tri-methyl-silane in the presence of hexa-methyl-disiloxane. The tri-methyl-silyl group and acetamido group are located on the same side of the pyran ring, showing an α-configuration glycoside. One of the tri-methyl-silyl groups is disordered over two orientations, with site-occupancy factors of 0.625 (9) and 0.375 (9). In the crystal, N-H⋯O hydrogen bonds link the mol-ecules ...[more]

1,2,3-Tri-O-acetyl-5-de-oxy-d-ribofuran-ose.

Project description:The title compound, C(11)H(16)O(7), was obtained from the breakage reaction of the glycosidic bond of 5'-de-oxy-2',3'-diacetyl-inosine. The ribofuran-ose ring has a C2-exo, C3-endo twist configuration. No alteration of the relative configuration compared with d-(-)-ribose is observed.

β-d-Galacto-pyranosyl-(1→4)-2-amino-2-de-oxy-α-d-gluco-pyran-ose hydro-chloride monohydrate (lactosamine).

Project description:The title compound, C12H24NO10 +·Cl-·H2O, (I), crystallizes in the monoclinic space group P21 and exists as a monohydrate of a monosubstituted ammonium chloride salt, with the reducing carbohydrate portion existing exclusively as the α-pyran-ose tautomer. The glycosidic bond geometry in (I) is stabilized by an intra-molecular hydrogen bond and is close to that found in crystalline α-lactose. All heteroatoms except gluco-pyran-ose ring O4 participate in an extensive hydrogen-bonding network, which propagates in all directions in the crystal structure of (I).

1-O-Acetyl-3,4,6-tri-O-benzyl-2-C-bromo-methyl-2-de-oxy-?-d-glucopyran-ose.

Project description:In the title compound, C30H33BrO6, the pyran-ose ring adopts a chair conformation. Two of the O-benzyl phenyl rings lie almost perpendicular to C/C/C/O plane formed by the ring atoms not attached to these O-benzyl phenyl rings, and form dihedral angles of 85.1?(2) and 64.6?(2)°, while the third O-benzyl phenyl ring is twisted so that it makes a dihedral angle 34.9?(2)° to this C/C/C/O plane. This twist is ascribed to the formation of an S(8) loop stabilized by a weak intra-molecular C-H?O hydrogen bond.

N-Benzyl-6-de-oxy-3,6-imino-methyl-ene-1,2,3,5-O-tetra-acetyl-?-d-1(S)-epiallo-furan-ose.

Project description:The mol-ecule of the title compound, C(22)H(27)NO(9), an azasugar derivative, consists of one benzene ring and two fused rings, which have the cis arrangement at the ring junctions, and gives a V-shaped geometry. The inter-planar angle between the five- and six-membered rings is 65.69?(11)°. The crystal structure is stablized by weak inter-molecular C-H?O hydrogen bonds.

Crystal structure of 6-azido-6-de-oxy-1,2-<i>O</i>-iso-propyl-idene-α-d-gluco-furan-ose.

Project description:Short syntheses to high Fsp 3 index natural-product analogues such as imino-sugars are of paramount importance in the investigation of their biological activities and reducing the use of protecting groups is an advantageous synthetic strategy. An iso-propyl-idene group was employed towards the synthesis of seven-membered ring imino-sugars and the title compound, C9H15N3O5, was crystallized as an inter-mediate, in which the THF ring is twisted and the dioxolane ring adopts an envelope conformation: the dihedral angle between the rings is 67.50 (13)°. In the crystal, the hydroxyl groups participate in O-H⋯(O,O) and O-H⋯N hydrogen-bonding inter-actions, which generate chains of mol-ecules propagating parallel to the a-axis direction. There is a notable non-classical C-H⋯O hydrogen bond, which cross-links the [100] chains into (001) sheets.

2-De-oxy-?-d-arabino-hexopyran-ose.

Project description:The title compound, C(6)H(12)O(5), is the ?-pyran-ose form of the reducing aldose 2-de-oxy-d-arabino-hexose. The six-membered pyran-ose ring adopts a (4)C(1) conformation, with the anomeric hy-droxy group in axial and the other substituents in equatorial positions. In the crystal, each of the four hy-droxy groups acts as an inter-molecular hydrogen-bond donor function, resulting in a three-dimensional hydrogen-bonded network.

Project description:X-ray crystallography showed that the title compound, C(6)H(12)O(5), crystallizes in the α-pyran-ose form with the six-membered ring in a chair conformation. The crystal structure exists as a three-dimensional hydrogen-bonded network of mol-ecules with each mol-ecule acting as a donor and aceptor for four hydrogen bonds. The absolute configuration was determined by the use of l-fucose as starting material.

Crystal structure of 6-de-oxy-α-l-psico-furan-ose.

Project description:The title compound, C6H12O5, was crystallized from an aqueous solution of 6-de-oxy-l-psicose (6-de-oxy-l-allulose, (3S,4S,5S)-1,3,4,5-tetra-hydroxy-hexan-2-one), and the mol-ecule was confirmed as α-furan-ose with a (3) T 4 (or E 4) conformation, which is a predominant tautomer in solution. This five-membered furan-ose ring structure is the second example in the field of the 6-de-oxy-ketohexose family. The cell volume of the title compound [742.67 (7) Å(3), Z = 4 at room temperature] is only 1.4% smaller than that of β-d-psico-pyran-ose, C6H12O6 (753.056 Å(3), Z = 4 at room temperature).
