(1S,3R,8R)-2,2-Dibromo-3,7,7,10-tetramethyltricyclo[6.4.0.01,3]dodec-9-en-11-one
The title compound, C16H22Br2O, 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 is built up from fused six- and seven-membered rings and an additional three-membered ring from the reaction of himachalene with dibromo-carbene. The six-membered ri...
متن کامل11-Hydroxy-9-(prop-2-en-1-yl)-9,10-dihydro-9,10-propanoanthracen-12-one
In the title compound, C(20)H(18)O(2), the central six-membered ring adopts a boat conformation and the terminal benzene rings make a dihedral angle of 42.66 (4)° with each other. In the crystal structure, the O-H group forms both an intra- and an inter-molecular O-H⋯O hydrogen bond; the former generates an S(5) ring and the latter leads to inversion-generated R(2) (2)(10) loops. The dimers are...

The title compound, C16H22Cl2O, was synthesized from β-himachalene (3,5,5,9-tetra-methyl-2,4a,5,6,7,8-hexa-hydro-1H-benzo-cyclo-heptene), which was isolated from the essential oil of the Atlas cedar (Cedrus Atlantica). The mol-ecule is built up from fused six- and seven-membered rings and an additional three-membered ring arising from the reaction of himachalene with di-chloro-carbene. The six-...

The absolute configuration of the title compound, C16H24O, has been deduced from the chemical pathway. The six-membered ring has a roughly half-chair conformation with the quaternary C atom as the flap. The seven-membered ring displays a chair conformation. In the crystal, there is a weak C-H⋯O hydrogen bond between the methyl-ene group of the cyclo-propane ring and the carbonyl group of a scre...

The title compound 1-OPBB, C(19)H(19)BrO(2), contains a dechlorinated and hydrogenated isodrin backbone with an anti-4-bromo-benzoate substituent at one of the methano bridges. The dihedral angle between the CO(2) ester plane and the benzene ring plane is 8.5 (2)°. In the crystal, the ester groups stack over benzene rings: the mol-ecules pack as conformational enanti-omers, with nearest paralle...
