Crystal structure of 5-O-benzoyl-2,3-O-iso-propyl-idene-d-ribono-1,4-lactone.

ABSTRACT: In the title compound, C₁₅H₁₆O₆, obtained from the acyl-ation reaction between 2,3-O-iso-propyl-idene-d-ribono-1,4-lactone and benzoyl chloride, the known absolute configuration for the lactone moiety of the ester substituent has been confirmed. The five-membered rings of the bicyclic lactone-dioxolane moiety both show envelope conformations and form a dihedral angle of 19.82 (7)° between the lactone ring and the benzene ring. In the crystal, mol-ecules of the acyl-ated sugar are linked by very weak inter-molecular C-H⋯O inter-actions, forming a three-dimensional network.

2,3-O-(S)-Benzyl-idene-2-C-methyl-d-ribono-1,4-lactone.

Project description:The crystal structure of the title compound, C(13)H(14)O(5), establishes (i) the (S) - rather than (R) - configuration at the acetal carbon and (ii) that both the acetal and the lactone form five- rather than six-membered rings; the absolute configuration is determined by the use of 2-C-methyl-d-ribono-1,4-lactone as the starting material. The compound consists of hydrogen-bonded chains of mol-ecules running along the a axis; there are no unusual packing features. Only classical hydrogen bonding has been considered.

Crystal structure of 1,1',2,2',4,4'-hexa-iso-propyl-magnesocene.

Project description:The title compound, 3Cp2Mg or [Mg(C14H23)2], was synthesized from the cor-res-ponding triiso-propyl-cyclo-penta-diene by treatment with n-butyl-sec-butyl-magnesium. The structural characterization by single-crystal X-ray diffraction revealed that the compound crystallizes in the triclinic space group P with half a mol-ecule per asymmetric unit and a staggered arrangement of the cyclo-penta-dienide ligands.

1-O-Benzyl-2,3-O-iso-propyl-idene-6-O-tosyl-α-l-sorbo-furan-ose.

Project description:In the title compound (systematic name{(3aS,5S,6R,6aS)-3a-[(benz-yloxy)meth-yl]-6-hy-droxy-2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxol-5-yl}methyl 4-methyl-benzene-sulfonate), C23H28O8S, the absolute structure and relative stereochemistry of the four chiral centres have been established by X-ray crystallography, with the absolute configuration inferred from the use of l-sorbose as the starting material. The central furan-ose ring adopts a slightly twisted envelope conformation (with the C atom bearing the methyl-benzene-sulfonate substituent as the flap) from which three substituents depart pseudo-axially (-CH2-O-benzyl, -OH and one acetonide O atom) and two substituents pseudo-equatorially (-CH2-O-tosyl and second acetonide O atom). The dioxalane ring is in a flattened envelope conformation with the fused CH C atom as the flap. In the crystal, mol-ecules pack in columns along [010] linked by O-H⋯O hydrogen bonds involving the furan-ose hy-droxy group and furan-ose ether O atom.

Crystal structure of 6-azido-6-de-oxy-1,2-O-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.

Crystal structure of 3-de-oxy-3-nitro-methyl-1,2;5,6-di-O-iso-propyl-idene-α-d-allo-furan-ose.

Project description:The title compound, C13H21NO7 {systematic name: (3aR,5S,6R,6aR)-5-[(R)-2,2-dimethyl-1,3-dioxolan-4-yl]-2,2-dimethyl-6-(nitro-meth-yl)tetra-hydro-furo[2,3-d][1,3]dioxole}, consists of a substituted 2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxolane skeleton. The furan-ose ring A adopts a (o)T 4 conformation. The fused dioxolane ring B and the substituent dioxolane ring C also have twisted conformations. There are no strong hydrogen bonds in the crystal structure: only weak C-H⋯O contacts are present, which link the mol-ecules to form a three-dimensional structure.

Crystal structure of 6-chloro-5-iso-propyl-pyrimidine-2,4(1H,3H)-dione.

Project description:In the mol-ecule of the title compound, C7H9ClN2O2, the conformation is determined by intra-molecular C-H⋯O and C-H⋯Cl hydrogen bonds, which generate S(6) and S(5) ring motifs. The isopropyl group is almost perpendicular to the pyrimidine ring with torsion angles of -70.8 (3) and 56.0 (3)°. In the crystal, two inversion-related mol-ecules are linked via a pair of N-H⋯O hydrogen bonds into R 2 (2)(8) dimers; these dimers are connected into chains extending along the bc plane via an additional N-H⋯O hydrogen bond and weaker C-H⋯O hydrogen bonds. The crystal structure is further stabilized by a weak π-π inter-action [3.6465 (10) Å] between adjacent pyrimidine-dione rings arranged in a head-to-tail fashion, producing a three-dimensional network.

Crystal structure of (Z)-3-(4-meth-oxy-benzyl-idene)-2,3-di-hydro-benzo[b][1,4]thia-zepin-4(5H)-one.

Project description:In the title compound, C17H15NO2S, the two C atoms linking the S and carbonyl C atoms of the seven-membered thia-zepine ring are disordered over two sites, with occupancies of 0.511 (4) and 0.489 (4); both disorder components adopt distorted twist-boat conformations. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link inverted-related mol-ecules into dimers, incorporating R 1 (2)(6) and R 2 (2)(8) ring motifs; the acceptor carbonyl O atom is bifurcated. These dimers are further linked by C-H⋯O hydrogen bonds, forming supra-molecular tapes running along the a axis.
