Crystal structure of ethyl (2S)-9-meth-oxy-2-methyl-4-oxo-3,4,5,6-tetra-hydro-2H- 2,6-methano-benzo[g][1,3,5]oxa-diazocine-11-carboxyl-ate.

ABSTRACT: In the title compound, C15H18N2O5, the meth-oxy-phenyl ring makes a dihedral angle of 84.70?(12)° with the mean plane of the tetra-hydro-pyrimidin-2(1H)-one ring. Both the pyran and tetra-hydro-pyrimidin-2(1H)-one rings have distorted envelope conformations with the carboxyl-ate-substituted C atom as the flap. In the crystal, mol-ecules are linked via pairs of N-H?O hydrogen bonds, forming zigzag chains propagating along [010], which enclose R (2) 2(8) ring motifs. The chains are linked by C-H?? inter-actions, forming a two-dimensional network parallel to (100).

rac-2-Methyl-3,4,5,6-tetra-hydro-2H-2,6-methano-1,3-benzoxazocin-4-one.

Project description:The title compound, C(12)H(13)NO(2), represents a conformationally restricted 2-pyridone analogue of 1,4-dihydro-pyridine-type calcium antagonists and was selected for a crystal structure determination in order to explore some aspects of drug-receptor inter-action. In the mol-ecule, two stereogenic centres are of opposite chirality, whereas a racemate occurs in the crystal. It was found that the formally aminic N atom of the heterocycle is essentially sp(2)-hybridized with the lone-pair electrons partially delocalized through conjugation with the adjacent carbonyl bond. As a result, the central pyridone ring assumes an unsymmetrical half-chair conformation. The critical 4-phenyl ring is fixed in a pseudo-axial and perpendicular orientation [dihedral angle 85.8?(1)°] with respect to the pyridone ring via an oxygen bridge. In the crystal a pair of centrosymmetric N-H?O hydrogen bonds connect mol-ecules of opposite chirality into a dimer. The dimers are packed by hydrophobic van der Waals inter-actions.

Crystal structure and Hirshfeld surface analysis of two 5,11-methano-benzo[<i>g</i>][1,2,4]triazolo[1,5-<i>c</i>][1,3,5]oxa-diazo-cine derivatives.

Project description:In the title compounds, 9-bromo-2,5-dimethyl-11,12-di-hydro-5H-5,11-methano-benzo[g][1,2,4]triazolo[1,5-c][1,3,5]oxa-diazo-cine, C13H13BrN4O (I), and 7-meth-oxy-5-methyl-2-(pyridin-4-yl)-11,12-di-hydro-5H-5,11-methano-benzo[g][1,2,4]tri-azolo[1,5-c][1,3,5]oxa-diazo-cine, C18H17N5O2 (II), the triazole ring is inclined to the benzene ring by 85.15 (9) and 76.98 (5)° in compounds I and II, respectively. In II, the pyridine ring is almost coplanar with the triazole ring, having a dihedral angle of 4.19 (8)°. In the crystal of I, pairs of N-H⋯N hydrogen bonds link the mol-ecules to form inversion dimers with an R 2 2(8) ring motif. The dimers are linked by C-H⋯π and C-Br⋯π inter-actions forming layers parallel to the bc plane. In the crystal of II, mol-ecules are linked by N-H⋯N and C-H⋯O hydrogen bonds forming chains propagating along the b-axis direction. The inter-molecular inter-actions were investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots, and the mol-ecular electrostatic potential surface was also analysed. The Hirshfeld surface analysis of I suggests that the most significant contributions to the crystal packing are H⋯H (42.4%) and O⋯H/H⋯O (17.9%) contacts. For compound II, the H⋯H (48.5%), C⋯H/H⋯C (19.6%) and N⋯H/H⋯N (16.9%) inter-actions are the most important contributions.

In the crystal, weak inter-molecular π-π stacking inter-actions are found between face-to-face naphthalene rings [centroid-centroid distance = 3.662 (7) Å].

Project description:In the crystal structure of the title compound, C(22)H(17)BrO(6), the quinone ring makes a dihedral angle of 81.84?(3)° with the benzene ring.

The terminal ethyl group of the -CO(2)CH(2)CH(3) group is disordered over two sets of sites with site-occupancy factors of 0.64?(1) and 0.36?(1). Inter-molecular O-H?O inter-actions further stabilize the crystal packing.

Project description:In the title compound, C35H31NO5, the piperidine ring has an envelope conformation, with the phenyl-substituted C atom adjacent to the methyl-ene C atom as the flap.

Ethyl 2-[4-(2-chloro-benzo-yl)-2,6-di-methyl-phen-oxy]ethano-ate.

Project description:The asymmetric unit of the title compound, C(19)H(19)ClO(4), contains two independent mol-ecules. The dihedral angles between the benzene rings are 63.41 (8) and 61.41 (9)°. Adjacent mol-ecules of different types are inter-connected in pairs through π-π inter-actions between their central benzene rings [centroid-centroid separation = 3.801 (2) Å, inter-planar spacing = 3.605 (2) Å, centroid shift = 1.204 (2) Å]. Finally, C-H⋯O hydrogen bonds link these dimers into bilayers parallel to (100).

Dipentyl 2,6-di-amino-benzo[1,2-b:4,5-b']di-furan-3,7-di-carboxyl-ate.

Project description:The title compound, C22H28N2O6, crystallizes with one half-mol-ecule in the independent unit, the mol-ecule being located on an inversion centre. The penthyl groups are in the all-trans conformation and an almost planar conformation of the whole mol-ecule is observed [maximum deviation from the least-squares plane through all non-H atoms is 0.0229?(17)?Å for an N atom]. The amino groups are involved in intra- and inter-molecular hydrogen bonds. Intra-molecular hydrogen bonding involving the amino group and ester carbonyl helps to lock the syn conformation of the ester with respect to the amino group. In the crystal, N-H?O hydrogen bonding involving the amino group and the furan and ester carbonyl O atoms self-assembles the mol-ecules into a two-dimensional hydrogen-bonded network parallel to (010) that displays inter-digital packing sustained by alk-yl-alkyl inter-actions.

Isoxazolium N-ylides and 1-oxa-5-azahexa-1,3,5-trienes on the way from isoxazoles to 2H-1,3-oxazines.

Project description:Theoretical and experimental studies of the reaction of isoxazoles with diazo compounds show that the formation of 2H-1,3-oxazines proceeds via the formation of (3Z)-1-oxa-5-azahexa-1,3,5-trienes which undergo a 6π-cyclization. The stationary points corresponding to the probable reaction intermediates, isoxazolium N-ylides, were located by DFT calculations at the B3LYP/6-31G(d) level only for derivatives without a substituent in position 3 of the isoxazole ring. These isoxazolium N-ylides are thermodynamically and kinetically very unstable. According to the calculations and experimental results 2H-1,3-oxazines are usually more thermodynamically stable than the corresponding open-chain isomers, (3Z)-1-oxa-5-azahexa-1,3,5-trienes. The exception are oxaazahexatrienes derived from 5-alkoxyisoxazoles, which are thermodynamically more stable than the corresponding 2H-1,3-oxazines. Therefore, the reaction of diazo esters with 5-alkoxyisoxazoles is a good approach to 1,4-di(alkoxycarbonyl)-2-azabuta-1,3-dienes. The reaction conditions for the preparation of aryl- and halogen-substituted 2H-1,3-oxazines and 1,4-di(alkoxycarbonyl)-2-azabuta-1,3-dienes from isoxazoles were investigated.
