Cholest-5-en-7-one
In the deca-hydro-phenanthrenone ring system of the title compound, C(27)H(44)O, the two cyclo-hexane rings adopt chair conformations, whereas the cyclo-hexene ring adopts an envelope conformation. The cyclo-pentane ring is twisted. In the crystal structure, mol-ecules are stacked along the a axis, but no significant inter-molecular inter-actions are observed.

In the title compound, C(34)H(51)NO(2), the dihedral angle between the planes of the phenyl ring and the carbonyl group is 9.30 (2)°. No significant inter-molecular inter-actions are observed in the crystal structure. The C(5)H(11) fragment is disordered over two positions with site occupancies of 0.611 (6) and 0.389 (6).
متن کامل3β-Chlorocholest-5-en-7-one
The title compound, C(27)H(43)ClO, is a steroid derivative composed of a saturated carbon fused-ring framework with an alkyl side chain. The A and C rings have chair conformations and the B and D rings assume half-chair conformations. The cholesterol side chain is fully extended with a gauche, trans conformation of the terminal methyl groups. In the crystal structure, the molecules are aligned ...

The title compound, C31H48O7, a polyoxygenated steroid, was obtained by chemical oxidation of 7-de-hydro-cholesteryl acetate. The mol-ecular geometry features trans A/B and C/D junctions at the steroid core with the acetyl groups in the equatorial position and a fully extended conformation for the alkyl side chain. A chair conformation is observed for rings A and C while ring B adopts a half-ch...
