7-Isopropyl-1,4a-dimethyl-1,2,3,4,4a,5,6,7,8,9,10,10a-dodeca-hydro-phenan-threne-1-carboxylic acid.

ABSTRACT: The title compound, C(20)H(32)O(2), has been isolated from hydrogenated rosin. There are two independent mol-ecules in the asymmetric unit. In each mol-ecule, the cyclo-hexane ring assumes a chair conformation, while the two cyclo-hexene rings adopt half-chair and envelope conformations. Inter-molecular O-H?O hydrogen bonding between carboxyl groups links pairs of independent mol-ecules into dimers.

Project description:The title compound, also known as isopimaric acid, C(20)H(30)O(2), was isolated from slash pine rosin. There are two unique mol-ecules in the unit cell. The two cyclo-hexane rings have classical chair conformations. The cyclo-hexene ring represents a semi-chair. The mol-ecular conformation is stabilized by weak intra-molecular C-H?O hydrogen-bonding inter-actions. The mol-ecules are dimerized through their carboxyl groups by O-H?O hydrogen bonds, forming R(2) (2)(8) rings.

(7-Isopropyl-1,4a-dimethyl-1,2,3,4,4a,-9,10,10a-octa-hydro-phenanthren-1-yl)-methanaminium 4-toluene-sulfonate.

Project description:In the title compound, C(20)H(32)N(+)·C(7)H(7)O(3)S(-), the configurations of the two chiral centers observed in the protonated cation are consistent with previous reports. In the crystal structure, weak inter-molecular N-H⋯O hydrogen bonds link ions into chains which develop along the a axis. The isopropyl group and four CH groups of the attached benzene ring are disordered approximately equally over two positions.

Crystal structure of 7-isopropyl-1,4a,N-trimethyl-1,2,3,4,4a,4b,5,6,7,8,10,10a-dodeca-hydro-phenanthrene-1-carb-ox-amide.

Project description:In the title compound, C26H37NO, a new derivative of di-hydro-abietic acid, the two cyclo-hexene rings adopt half chair conformations, whereas the cyclo-hexane ring has a chair conformation. Each of the methyl groups is in an axial position with respect to the tricyclic hydro-phenanthrene residue. In the crystal packing, methyl-ene-C-H⋯π(phen-yl) inter-actions lead to supra-molecular helical chains along [010]; the amide-H atom does not form a significant inter-molecular inter-action owing to steric pressure.

Project description:The title compound, C(27)H(34)ClN, has been synthesized from 4-chloro-benzaldehyde and dehydro-abietylamine. There are two unique mol-ecules in the unit cell. Each mol-ecule has three chiral centres, which exhibit R, S and R absolute configurations. The two cyclo-hexane rings form a trans ring junction with classical chair and half-chair conformations.

1,4a-Dimethyl-6-methyl-ene-5-(5,5,6,6-tetra-cyano-2-methyl-cyclo-hex-2-enylmeth-yl)deca-hydro-naphthalene-1-carboxylic acid: a trans-communic acid derivative.

Project description:In the search for cancer chemopreventive agents, we have studied the Diels-Alder reaction of trans-communic acid with tetra-cyano-ethyl-ene in the presence of SiO(2) as catalyst. The title cycloadduct, C(26)H(30)N(4)O(2), was obtained in 75% yield. The mol-ecules are arranged in pairs through O-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. Both the fused cyclohexyl rings adopt a chair conformation, whereas the nonfused ring adopts a half-chair conformation.

(±)-trans-3-Oxo-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthrene-10a-carboxylic acid: catemeric hydrogen bonding in a ?-keto acid.

Project description:The title compound, C(15)H(16)O(3), aggregates as hydrogen-bonded catemers progressing from each carboxyl to the ketone of a screw-related neighbor [O?O = 2.6675?(14)?Å and O-H?O = 170°]. Two parallel centrosymmetrically related single-strand hydrogen-bonding helices proceed through the cell in the b-axis direction. The packing includes three inter-molecular C-H?O=C close contacts, involving both the ketone and the carboxyl group. The structure is isomorphous with that of the previously described ?(4) ?,?-unsaturated ketone.

(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.

(4aS,10aS)-7-Hydr-oxy-8-isopropyl-1,1,4a-trimethyl-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthrene: a new diterpenoid compound.

Project description:The new title diterpenoid compound, C(20)H(30)O, is a natural product isolated from Tetra-clinis articulata wood via chloro-form extraction. The asymmetric unit contains four mol-ecules with the same S,S configuration, deduced from the chemical synthesis. Indeed, an overlay analysis, calculated using structure-matching software, shows that the four mol-ecules can be superimposed. The central ring has a half-chair conformation, whereas the saturated ring displays a chair conformation.
