(1R,2S,4S,4aS,8S,8aS)-4-Hy-droxy-8,8a-dimethyl-10-oxo-2,3,4,7,8,8a-hexa-hydro-1H-4a,1-(ep-oxy-methano)-naphthalen-2-yl acetate.

ABSTRACT: The title compound, C15H20O5, presents a bis-norsesquiterpene skeleton, with a trans-deca-line backbone constrained by the lactone bridge. The ?-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.

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 ...[more]

Crystal structure of 2-[(1R,2R,4aS,8aS)-2-hy-droxy-2,5,5,8a-tetra-methyl-deca-hydro-naphthalen-1-yl]-N-(o-tol-yl)acetamide.

Project description:The title compound, C23H35NO2, is an amide derivative of the lactone (+)-sclareolide, and was synthesized from natural sclareol. In the mol-ecular structure, the two six-membered rings (A and B) of the labdane skeleton are trans-fused, and adopt chair conformations. There is an intra-molecular N-H⋯O hydrogen bond present forming an S(7) ring motif. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into helical chains propagating along the b-axis direction. The chains are linked via C-H⋯π inter-actions, forming a three-dimensional structure.

(2R,3R,4aS,6S,7S,8aS)-4a-Fluoro-8a-hy-droxy-perhydro-naphthalene-2,3,6,7-tetrayl tetraacetate.

Project description:The title compound, C(18)H(25)FO(9), exhibits a similar unit cell and packing to the ? polymorph of axial 4a,8a-dihy-droxy-per-hydro-naph-tha-lene-2,3,6,7-tetrayl tetraacetate. The carbonyl O atoms of two of the four acetate groups in the molecule are disordered over two sites with occupancy ratios of 0.59?(4):0.41?(4) and 0.57?(6):0.43?(6). Crystal packing is effected via inter-molecular O-H?O hydrogen bonds, which link the tetra-acetate mol-ecules into tapes along the c axis.

Project description:The title compound, C(16)H(16)Cl(2)N(2), was synthesized by the condensation reaction between 4,5-dichloro-o-phenyl-ene-diamine and (1R)-(-)-camphorquinone in boiling acetic acid. The two crystallographically independent mol-ecules in the unit cell are related by a pseudo-inversion center.

(1R*,2R*,4S*,5R*,6R*,8S*)-4,8-Dimethyl-2,6-diphenyl-bicyclo-[3.3.1]nonane-2,6-diol.

Project description:The racemic title compound, C(23)H(28)O(2), crystallizes in the space group C2/c as a layered structure in which a centrosymmetric three hydrogen bond sequence links four molecules. Both hydroxy groups are involved in this arrangement, but they differ in that one participates in two hydrogen bonds while the other takes part in only one. Between layers, the aromatic rings take part in edge-face interactions [shortest C-H⋯C distances 3.04, 3.10 and 3.12 Å and angle between normal to planes 86.7(2)°], forming a centrosymmetric dimer. The lattice is further stabilized by C-H⋯π interactions involving both methyl (shortest C⋯C 3.82 and 3.97 Å) and methylene (shortest C⋯C 3.60 Å) groups.

(1R*,2S*,4S*,5R*)-Cyclo-hexane-1,2:4,5-tetra-carb-oxy-lic dianhydride.

Project description:The title compound, C(10)H(8)O(6), a promising raw material to obtain colorless polyimides which are applied to microelectronic and optoelectronic devices, adopts a folded conformation in which the dihedral angle between the two anhydro rings is 55.15?(8)°. The central six-membered ring assumes a conformation inter-mediate between boat and twist-boat. In the crystal, mol-ecules are linked by weak C-H?O inter-actions, forming a layer parallel to the bc plane.

Project description:In the chiral title compound, C(18)H(28)O(3), the two six-membered rings of the perhydronaphthalenone adopt a rigid chair-chair conformation and the five-membered dioxolanyl ring adopts an envelope conformation. The crystal structure is stabilized only by weak inter-actions.

2-[(3S,3aS,5R,8S,8aS)-3,8-Di-methyl-hexa-hydro-1H,4H-3a,8a-ep-oxy-azulen-5-yl]propan-2-ol.

Project description:Four independent mol-ecules (A-D) comprise the asymmetric unit of the title compound, C15H26O2, which differ only in the relative orientations of the terminal -C(Me)2OH groups [e.g. the range of Cmethyl-ene-Cmethine-Cquaternary-Ohy-droxy torsion angles is 52.7?(7)-57.1?(6)°, where the Cmethyl-ene atom is bound to an epoxide C atom]. The five-membered rings adopt envelope conformations, with the methyl-ene C atom adjacent to the methine C atom being the flap atom in each case. In each mol-ecule, the conformation of the seven-membered ring is a half-chair, with the Cmethyl-ene-Cmethine bond, flanked by methyl-ene C atoms, being the back of the chair. Supra-molecular helical chains along the b axis are found in the crystal packing, sustained by hy-droxy-epoxide O-H?O hydrogen bonding. Mol-ecules of A self-associate into a chain as do those of D. A third independent chain comprising B and C mol-ecules is also formed. The studied crystal is a pseudo-merohedral twin (minor component ca 21%).

Project description:In the title compound, C15H25NO2, all three six-membered rings adopt chair conformations.

The methyl substituent occupies the sterically preferrable equatorial position. In the crystal, mol-ecules form infinite [100] chains via O-H?N hydrogen bonds.
