(4aR,8aR)-2,3-Diphenyl-4a,5,6,7,8,8a-hexa-hydro-quinoxaline.

ABSTRACT: The title mol-ecule, C(20)H(20)N(2), is chiral; the absolute configuration follows from the known chirality of the input reagents. In addition to van der Waals forces, C-H?? ring inter-actions are also present. The angle between the planes of the phenyl rings is 65.6?(1)°. The heterocyclic ring of the quinoxaline system has a twist-boat configuration, while the cyclohexane ring has a chair configuration.

The title mol-ecule, C(20)H(20)N(2), is chiral; the absolute configuration follows from the known chirality of the input reagents. In addition to van der Waals forces, C-H⋯π ring inter-actions are also present. The angle between the planes of the phenyl rings is 65.6 (1)°. The heterocyclic ring of the quinoxaline system has a twist-boat configuration, while the cyclohexane ring has a chair configuration. ...[more]

rac-(4aR,8aR)-2,3-Diphenyl-4a,5,6,7,8,8a-hexa-hydro-quinoxaline.

Project description:The structure of the title racemic compound, C(20)H(20)N(2), shows close similarity to that of the enanti-omerically pure (4aR,8aR)-2,3-diphenyl-4a,5,6,7,8,8a-hexa-hydro-quinoxaline [Wang & Ye (2008 ?). Acta Cryst. E64, o359-o359]. The similarity applies to the unit-cell parameters as well as to the packing of the constituent mol-ecules. Similar packing is conditioned by a lack of directed inter-molecular inter-actions such as hydrogen bonds in either structure.

Project description:In the title compound, C(20)H(20)N(2), the quinoxaline ring adopts a very distorted half-chair conformation [N=C-C=N = 22.7 (2)° for the nominally coplanar atoms] and the cyclo-hexane ring adopts a chair conformation. The quinoxaline and cyclo-hexane rings are cis-fused. The two phenyl rings form a dihedral angle of 63.88 (7)°.

(2S,4aR,3S,8aR,9R,10R)-1,4-Diallyl-2,3-diphenyl-perhydro-quinoxaline.

Project description:In the title compound, C(26)H(32)N(2), the cyclo-hexane and piperazine rings each adopt a chair conformation. Both phenyl rings and the two propen-3-yl residues are in equatorial positions. There are no C-H⋯N hydrogen bonds nor π-π inter-actions between the aromatic rings. The absolute configuration was assigned with reference to the starting material.

Project description:In the title compound, C(28)H(27)NO(2), the oxazinone ring adopts a twist-boat conformation and the cyclo-hexene ring has a twisted envelope conformation. The crystal structure is stabilized by weak non-classical inter-molecular C-H⋯O hydrogen bonds.

(4R*,4aR*,7aS*)-5-Oxo-6-phenyl-4a,5,6,7,7a,8-hexa-hydro-4H-furo[2,3-f]isoindole-4-carb-oxy-lic acid.

Project description:The asymmetric unit of the title compound, C(17)H(15)NO(4), contains two independent mol-ecules with similar geometric parameters. In both mol-ecules, the conformation of the cyclo-hexene ring is half-chair, while the pyrrolidinone ring adopts an envelope conformation with the γ-carbon atom of the α-pyrrolidinone ring as the flap. In the crystal, O-H⋯O hydrogen bonds between the carb-oxylic and carbonyl groups link alternate independent mol-ecules into chains propagating in the b-axis direction. The crystal packing also features weak C-H⋯π inter-actions.

(±)-(4aR,5R,8S,8aR)-8-(tert-Butyl-dimethyl-sil-yloxy)-2,5,8a-trimethyl-4a,5,8,8a-tetra-hydro-naphthalene-1,4-dione.

Project description:In the title compound, C19H30O3Si, both rings adopt a half-boat conformation. Overall, the mol-ecule approximates a U-shape as the cyclo-2-ene-1,4-dione and butyl-dimethyl-sil-yloxy substituents lie to the same side of the central cyclo-hexene ring; the methyl substituent lies to the other side of the mol-ecule. In the crystal, linear supra-molecular chains along the b axis are sustained by C-H?O inter-actions.

The cyclo-hexene ring has a half-chair conformation, whereas the cyclo-hexane ring displays a chair conformation.

Crystal structure and features of 3',8-di-benzyl-idene-4a,5,6,7,8,8a-hexa-hydro-2'<i>H</i>-spiro-[chromene-2,1'-cyclo-hexa-n]-2'-one.

Project description:The synthesis and crystal structure of the title compound, C28H28O2, are reported. The C=C-C-C torsion angles in the phenyl-methyl-idene units are 166.6?(3) and -48.0?(4)°. In the crystal, mol-ecules form a three-dimensional network by means of weak C-H?O hydrogen bonds. The most important contributions to the crystal structure are the H?H inter-actions (68.8%), while the H?O contacts account for 4.5%.

Project description:The title compound, C(14)H(24)O(2), was synthesized from ilicic acid, which was isolated from the aerial part of Inula Viscosa- (L) Aiton [or Dittrichia Viscosa- (L) Greuter]. The mol-ecule contains two fused six-membered rings, which both display a chair conformation. In the crystal, mol-ecules are linked into chains propagating along the b axis by inter-molecular O-H⋯O hydrogen bonds.

Synthesis and crystal structure of (2S,4aR,8aR)-6-oxo-2,4a,6,8a-tetra-hydro-pyrano[3,2-b]pyran-2-carboxamide.

Project description:The pyran-opyran amide (2S,4aR,8aR)-6-oxo-2,4a,6,8a-tetra-hydro-pyrano[3,2-b]pyran-2-carboxamide, C9H9NO4, 3, was prepared by a chemoselective hydration of the corresponding nitrile, 2, using a heterogeneous catalytic method based on copper(II) supported on mol-ecular sieves, in the presence of acetaldoxime. Compound 3 belongs to a new class of pyran-opyrans that possess anti-bacterial and phytotoxic activity. Crystallographic analysis of 3 shows a bent structure for the cis-fused bicyclic pyran-opyran, similar to nitrile 2. Evidence of an intra-molecular hydrogen bond involving the amide group and ring oxygen was not observed; however, two separate inter-molecular hydrogen-bonding inter-actions were observed between the amide hydrogen atoms and adjacent carbonyl oxygen atoms along the b- and a-axis directions. The latter inter-action may also be supported by an inter-molecular C-H?O hydrogen bond. The lattice is filled out by close-packed layers of this hydrogen-bonded network along the c-axis direction, related from one to the next by a 21 screw axis.
