1,3-Dioxo-2,3-dihydro-1H-isoindol-2-yl 2,3,4-tri-O-acetyl-?-d-xyloside.

ABSTRACT: The title compound, C(19)H(19)NO(10), was obtained from the reaction of ?-d-1-bromo-2,3,4-tri-O-acetylxylose with N-hy-droxy-phthalimide in the presence of potassium carbonate. The asymmetric unit contains two independent mol-ecules, in which the O-CH-O-N torsion angles are 73.0?(4) and 65.0?(4)°. The hexa-pyranosyl rings adopt chair conformations and the substituent groups are in equatorial positions. In the crystal, mol-ecules are linked by nonclassical C-H?O hydrogen bonds.

The title compound, C(19)H(19)NO(10), was obtained from the reaction of α-d-1-bromo-2,3,4-tri-O-acetylxylose with N-hy-droxy-phthalimide in the presence of potassium carbonate. The asymmetric unit contains two independent mol-ecules, in which the O-CH-O-N torsion angles are 73.0 (4) and 65.0 (4)°. The hexa-pyranosyl rings adopt chair conformations and the substituent groups are in equatorial positions. In the crystal, mol-ecules are linked by nonclassical C-H⋯O hydrogen bonds. ...[more]

Project description:The asymmetric unit of the title compound, C(27)H(16)F(2)N(2)O(4), consists of two crystallographically independent mol-ecules (A and B). In mol-ecule B, the isoindoline-1,3-dione ring system is disordered over two set of sites with a site-occupancy ratio of 0.658 (12):0.342 (12). In mol-ecule A, the fluoro-substituted benzene rings make dihedral angles of 18.36 (8) and 46.37 (8)° with the central benzene ring, whereas the corresponding angles are 40.90 (8) and 52.89 (9)° in mol-ecule B. The isoindoline ring system in mol-ecule A and the major and minor components of the disordered isoindoline ring system in mol-ecule B make dihedral angles of 58.50 (4), 54.13 (16) and 70.01 (28) °, respectively, with their attached benzene rings, linked through the amide group. An intra-molecular O-H⋯O hydrogen bond generates an S(6) ring in each mol-ecule. In the crystal, mol-ecules are linked by N-H⋯O, C-H⋯F and C-H⋯O hydrogen bonds into sheets lying parallel to the bc plane. The crystal studied was a non-merohedral twin with a refined twin component ratio of 0.9316 (8):0.0684 (8).

In the crystal, mol-ecules are connected via weak inter-molecular C-H?O hydrogen bonds, forming a two-dimensional network. The ethyl group is disordered over two sets of sites with a refined occupancy ratio of 0.502?(12):0.498?(12).

Ethyl 2-[1,3-dioxo-6-(piperidin-1-yl)-2,3-dihydro-1H-benz[de]isoquinolin-2-yl]acetate.

Project description:In the title compound, C(21)H(22)N(2)O(4), the naphthalimide unit is almost planar (r.m.s. deviation = 0.081Å). The carboximide N atom and the five C atoms of the eth-oxy-carbonyl-methyl substituent also lie close to a common plane (r.m.s. deviation = 0.119Å), which subtends an angle of 71.06?(8)° to the naphthalamide plane. The piperidine ring adopts a chair conformation. In the crystal, inter-molecular C-H?O hydrogen bonds link the mol-ecules into zigzag chains along the a axis.

2-(tert-Butoxy-carbonyl-amino)-6-(1,3-dioxo-1H-2,3-dihydro-benzo[de]isoquinolin-2-yl)hexa-noic acid.

Project description:In the title naphthalimide derivative, C(23)H(26)N(2)O(6), the 1,8-naphthalimide system is essentially planar [maximum deviation = 0.0456?(16)?Å]. A characteristic pattern of alternating long and short C-C bond lengths is observed in the 1,8-naphthalimide unit. The mean planes through the methyl carbamate and acetic acid groups form dihedral angles of 42.30?(9) and 61.59?(9)°, respectively, with the 1,8-naphthalimide plane. In the crystal structure, inter-molecular O-H?O and C-H?O hydrogen bonds link neighbouring mol-ecules, forming R(2) (2)(9) hydrogen-bond ring motifs. These rings are further inter-connected by inter-molecular N-H?O and C-H?O hydrogen bonds into a three-dimensional supra-molecular network.

4-Butyl-1-(2,3,4-tri-O-acetyl-?-l-fuco-pyranos-yl)-1H-1,2,3-triazole.

Project description:The title compound, C(18)H(27)N(3)O(7), was synthesized by Cu(I)-catalysed coupling of an azide with an alkyne as part of a study into the synthesis of N-glycosyl-1,2,3-triazoles. The crystal structure confirms the selective formation of the ?-conformer of the pyran-ose N-glycoside, thus confirming the retention of stereochemistry during heterocycle formation with the N-glycosyl triazole group occupying the equatorial position at the anomeric C atom. The structure exhibits two crystallographically independent mol-ecules (A and B) with essentially identical conformations with a weighted r.m.s. deviation of only 0.09?Å. The mol-ecules are arranged in layers with hydro-phobic and more polar sections built from the butyl triazole units on the one hand and the more polar moieties dominated by the carbohydrate units on the other. Within the polar layers, inter-molecular inter-actions are dominated by a three-dimensional network of weak C-H?O hydrogen bonds with the acetyl keto O atoms as the hydrogen-bond acceptors. The triazole units inter-act with each other via C-H?N hydrogen bonds which connect the mol-ecules into two infinite chains of mol-ecules made up of either A mol-ecules or B mol-ecules that stretch parallel to each other along [100]. Between the butyl groups no directional inter-actions are observed.
