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

ABSTRACT: 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)°.

Project description: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.

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.

(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.

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%.

(4bS,8aS)-1-Isopropyl-4b,8,8-trimethyl-4b,5,6,7,8,8a,9,10-octa-hydro-phenan-thren-2-yl acetate.

Project description:The hemisynthesis of the title compound, C22H32O2, was carried out through direct acetyl-ation reaction of the naturally occurring diterpene totarol [systematic name: (4bS,8aS)-4b,8,8-trimethyl-1-propan-2-yl-5,6,7,8a,9,10-hexa-hydro-phen-an-thren-2-ol]. The mol-ecule is built up from three fused six membered rings, one saturated and two unsaturated. The central unsaturated ring has a half-chair conformation, whereas the other unsaturated ring displays a chair conformation. The absolute configuration is deduced from the chemical pathway. The value of the Hooft parameter [-0.10 (6)] allowed this absolute configuration to be confirmed.

Project description:The title compound, C15H20O5, presents a bis-norsesquiterpene skeleton, with a trans-deca-line backbone constrained by the lactone bridge. The α-hy-droxy substituent and the methyl group belonging to the two deca-line rings are in axial positions, whereas the other methyl group and the acyl group occupy the sterically preferred equatorial positions. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond. In the crystal, mol-ecules are linked into chains along [010] by O-H⋯O hydrogen bonds.
