ABSTRACT: In the title compound, C(30)H(52)O(5), the three six-membered rings are in chair conformations, the five-membered ring is in an envelope form and the tetra-hydro-furan ring has a conformation inter-mediate between half-chair and sofa. Intra-molecular O-H?O hydrogen bonds may influence the conformation of the mol-ecule. In the crystal, mol-ecules are linked by inter-molecular O-H?O hydrogen bonds, forming a three-dimensional network.

(1S,3R,8S,9R,10S)-2,2-Dichloro-3,7,7,10-tetra-methyl-9,10-ep-oxy-tricyclo-[6.4.0.0]dodeca-ne.

The mol-ecule forms an extended sheet of two fused rings which exhibit different conformations. The six-membered ring has a half-chair conformation, while the seven-membered ring displays a chair conformation; the dihedral angle between the two rings is 38.2?(1)°.

19β,28-Ep-oxy-18α-olean-3β-ol.

Project description:The title triterpene, C(30)H(50)O(2), is an 18α-oleanane derivative prepared by the Wagner-Meerwein rearrangement of betulin with Bi(OTf)(3).xH(2)O (OTF is trifluoromethanesulfonate). There are two symmetry-independent mol-ecules in the asymmetric unit that show no significant differences concerning bond lengths and angles. The conformation of the six-membered rings is close to a chair form, while the five-membered epoxide rings adopt envelope conformations. All rings are trans-fused. In the crystal, mol-ecules are held together by O-H⋯O hydrogen bonds. A quantum-mechanical ab initio Roothan Hartree-Fock calculation on the isolated mol-ecule gives values for bond lengths and valency angles close to the experimental values. The calculations also reproduce well the mol-ecular conformation with calculated puckering parameters that match well the observed values.

Project description:The title compound, C16H24Br2O, was synthesized from β-himachalene (3,5,5,9-tetra-methyl-2,4a,5,6,7,8-hexa-hydro-1H-benzocyclo-heptene), which was isolated from the essential oil of the Atlas cedar (Cedrus atlantica). The mol-ecule contains fused six- and seven-membered rings, each linked to a three-membered ring. The six-membered ring has a half-chair conformation, while the seven-membered ring displays a chair conformation. The dihedral angle between the mean planes through the six- and seven-membered rings is 39.55 (12)°. The two three-membered rings, linked to the six- and seven-membered rings, are nearly perpendicular to the six-membered ring, making dihedral angles of 78.6 (2) and 80.5 (2)°, respectively. The absolute structure was established unambiguously from anomalous dispersion effects. In the crystal, each mol-ecule is linked to its symmetry-equivalent partner by C-H⋯O hydrogen bonds, forming zigzag chains parallel to [100].

Project description:The title compound, C(30)H(50)O(5), was isolated from the bark of Aglaia smithii.

The cyclo-hexane rings in both mol-ecules adopt chair conformations, whereas the cyclo-pentane and tetra-hydro-furan rings adopt envelope conformations. The independent mol-ecules are linked into a layer parallel to (010) by O-H?O hydrogen bonds.
