7-Isopropyl-1,4a-dimethyl-1,2,3,4,4a,5,6,7,8,9,10,10a-dodecahydrophenanthrene-1-carboxylic acid
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 di...

The title compound, C(15)H(16)N(2)O(4), was synthesized from a mixture of α-himachalene (2-methyl-ene-6,6,9-trimethyl-bicyclo-[5.4.O(1,7)]undec-8-ene) and β-himachalene (2,6,6,9-tetra-methyl-bicyclo-[5.4.0(1,7)]undeca-1,8-diene) which were isolated from an oil of the Atlas cedar (Cedrus atlantica). The asymmetric unit contains two independent mol-ecules. In each of the two mol-ecules, two O ato...

The title compound, C15H17NO2, was synthesized from a mixture of α-himachalene (2-methyl-ene-6,6,9-tri-methylbi-cyclo-[5.4.0(1,7)]undec-8-ene) and β-himachalene (2,6,6,9-tetra-methylbi-cyclo-[5.4.0(1,7)]undeca-1,8-diene), which were isolated from an oil of the Atlas cedar (Cedrus Atlantica). The naphthalene ring system makes dihedral angles of 68.6 (2) and 44.3 (2)°, respectively, with its atta...
متن کامل(7-Isopropyl-1,4a-dimethyl-1,2,3,4,4a,-9,10,10a-octahydrophenanthren-1-yl)methanaminium 4-toluenesulfonate
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 equal...
متن کاملSYNTHESIS OF (k) - 6,8-DIHYDROXY-3- ISOPROPYL-7-METHYLISOCHROMAN
The title isochroman ( 8 ) was synthesized as a suitable substrate for acetoxylation studies leading to an intermediate of type (4), expected to afford, on condensation with diketen, the fungal metabolite "rotiorin" type linear product (1). Cyclocondensation of alcohol (6), obtained by the reduction of ketone (5) with paraform in the presence of anhydrous aluminum chloride afforded the dim...
