4-Nitro-phenyl ?-l-rhamnopyran-oside hemihydrate.

ABSTRACT: In the title compound, C(12)H(15)NO(7)·0.5H(2)O, there are two independent mol-ecules in the asymmetric unit, together with one water molecule. The pyran-oside rings each have close to a (1)C(4) chair conformation and the nitro groups are almost coplanar with the benzene rings. The water mol-ecule links the two independent mol-ecules through O-H?O hydrogen bonds. All the hydroxyl groups are involved in hydrogen-bond inter-actions, giving rise to a three-dimensional network.

2-Phenyl-ethyl 1-thio-?-d-galactopyran-oside hemihydrate.

Project description:The title compound, C(14)H(20)O(5)S·0.5H(2)O, crystallizes with two organic mol-ecules and a solvent water mol-ecule in the asymmetric unit. In both mol-ecules, the hexa-pyranosyl rings adopt a slightly distorted chair conformation ((5)C(2)) with four substituents in equatorial positions and one substituent in an axial position. The main difference between the organic mol-ecules is the dihedral angle between the phenyl ring and the best plane defined by the O-C(1)-C(2)-C(3) atoms (r.m.s deviations = 0.003 and 0.043?Å) of the hexa-pyranosyl rings [47.4?(4) and 86.5?(4)°]. In the asymmetric unit, mol-ecules are linked by two strong O-H?O hydrogen bonds. In the crystal, the components are linked by a total of 10 distinct O-H?O hydrogen bonds, resulting in the formation of a two-dimensional network parallel to the ab plane.

Phenyl 2,3-O-isopropyl-idene-1-thio-α-d-rhamnopyran-oside.

Project description:In the title compound, C(15)H(20)O(4)S, a dioxolane ring is fused to the pyran ring of the sugar which carries a thio-phenyl substituent on the anomeric C atom. The dioxolane ring adopts an envelope conformation and the pyran ring system a distorted (4)C(1) chair. The structure is stabilized by O-H⋯O hydrogen bonds, forming centrosymmetric dimers that generate an R(2) (2)(10) ring motif. Additional C-H⋯O inter-actions form an extended network. Two C atoms of the phenyl ring are disordered over two positions; the site occupancy factors are ca. 0.7 and 0.3.

2,3,4,6-Tetra-O-benzoyl-4-nitro-phenyl-1-thio-α-d-mannopyran-oside-dichloro-methane-diethyl ether mixed solvate (1/0.53/0.38).

Project description:The title compound, C(40)H(31)NO(11)S·0.53CH(2)Cl(2)·0.38C(4)H(10)O, was synthesized in two steps from mannose penta-acetate and single crystals were grown by slow evaporation. The structure was determined by single-crystal X-ray diffraction, confirming the α-configuration of the anomeric thioaryl substituent. The asymmetric unit contains two crystallographically distinct mol-ecules of the carbohydrate. The central pyran-ose rings of these are geometrically similar, but there are differences in the orientations of the benzoate substituents.

4-Methoxy-phenyl 2,3,4,6-tetra-O-acetyl-1-thio-α-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 α 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.

Crystal structure of 4-nitro-phenyl 6-<i>O</i>-ethyl-β-d-galacto-pyran-oside monohydrate.

Project description:The synthesis and crystal structure of the title compound, C14H19NO8·H2O, prepared in three steps from 6-O-ethyl-1,2;3,4-di-O-iso-propyl-idene-α-d-galacto-pyran-ose using protecting-group strategies employed in carbohydrate chemistry, is reported. The asymmetric unit consists of a single galactoside mol-ecule, in which the pyran-oid ring has a 4C1 conformation and the 4-nitro-phenyl moiety is essentially planar. In the crystal, each carbohydrate is surrounded by other d-galactose residues and water mol-ecules, linked by O-H⋯O hydrogen bonds involving all hy-droxy groups, giving a two-dimensional substructure lying parallel to (100) and extended into three dimensions by C-H⋯O inter-actions.

4-Carbamoylpiperidinium phenyl-acetate hemihydrate.

Project description:The asymmetric unit of the title compound, C(6)H(13)N(2)O(+)·C(8)H(7)O(2) (-)·0.5H(2)O, comprises two isonipecotamide cations, two phenyl-acetate anions and a water mol-ecule of solvation. The hydrogen-bonding environments for both sets of ion pairs are essentially identical with the piperidinium and amide 'ends' of each cation involved in lateral heteromolecular hydrogen-bonded cyclic N-H?O associations [graph set R(2) (2)(11)] which incorporate a single carboxyl O-atom acceptor. These cyclic motifs enclose larger R(5) (5)(21) cyclic systems, forming sheet substructures which lie parallel to (101) and are linked across b by the single water mol-ecule via water O-H?O(c) (c = carboxylate) associations, giving a duplex-sheet structure.

rac-[2-(Dicyclohexylphosphanyl)phenyl](phenyl)phosphinic diisopropyl-amide-borane hemihydrate.

Project description:In the title compound, C(30)H(48)BNOP(2)·0.5H(2)O, the water molecule is disordered about an inversion centre. Both phospho-rus atoms shows distortions in their tetra-hedral environments with the cyclo-hexyl substituents disordered over two orientations in a 0.851 (3):0.149 (3) occupancy ratio. The crystal structure is assembled via O-H⋯O inter-actions between pairs of phosphininc amide mol-ecules and water molecules, creating hydrogen-bonded dimers with graph-set R(2) (4)(8) along [001]. Weak C-H⋯O inter-actions are also observed.

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 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.
