(1E,4E)-1-(3-Nitrophenyl)-5-phenylpenta-1,4-dien-3-one
In the title compound, C(17)H(13)NO(3), the dihedral angle between the benzene rings is 31.21 (5)°. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds occur. A C-H⋯π inter-action is also indicated.

In the title mol-ecule, C17H12F2O3, the dihedral angle between the benzene rings is 8.6 (2)°. In the crystal, two pairs of O-H⋯O hydrogen bonds connect the mol-ecules into inversion dimers. In addition, weak C-H⋯F hydrogen bonds link the dimers into a two-dimensional network parallel to (10-4). The carbonyl O atom is an acceptor for two weak intra-molecular hydrogen bonds.

In the mol-ecule of the title compound, C(15)H(13)FN(2)O, the phenyl and fluorophenyl rings are oriented at a dihedral angle of 77.92 (3)°. The pyrazolidine ring adopts an envelope conformation. An intra-molecular C-H⋯N hydrogen bond results in the formation of a five-membered ring adopting an envelope conformation. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link t...

THE TITLE COMPOUND [SYSTEMATIC NAME: 17-(5,6-di-methyl-hept-6-en-2-yl)-4,4,10,13,14-penta-methyl-1,5,6,10,11,12,13,15,16,17-deca-hydro-2H-cyclo-penta-[α]phenanthren-3(4H,9H,14H)-one], C(31)H(50)O, is a triterpenoid which was isolated from Skimmia laureola. The three six-membered rings adopt chair, slightly distorted half-chair and distorted boat conformations, and the five-membered ring is in a...
متن کامل5α-Pregna-1,20-dien-3-one
The title compound, C(21)H(30)O, was isolated from the soft coral Sinularia sp. The mol-ecule contains four alicyclic rings, all trans-fused, among which three six-membered rings are in different distorted chair conformations while a five-membered ring assumes an envelope form.
