(1R,4R,6S,7R)-5,5-Di­bromo-1,4,8,8-tetra­methyl­tri­cyclo­[5.4.1.0(4,6)]dodecan-12-one

The title compound, C(16)H(24)Br(2)O, was synthesized from the reaction of β-himachalene (3,5,5,9-tetra­methyl-2,4a,5,6,7,8-hexa­hydro-1H-benzo­cyclo­heptene), which was isolated from Atlas cedar (Cedrus atlantica). The asymmetric unit contains two independent mol­ecules with similar conformations....

Descripción
Sumario:The title compound, C(16)H(24)Br(2)O, was synthesized from the reaction of β-himachalene (3,5,5,9-tetra­methyl-2,4a,5,6,7,8-hexa­hydro-1H-benzo­cyclo­heptene), which was isolated from Atlas cedar (Cedrus atlantica). The asymmetric unit contains two independent mol­ecules with similar conformations. Each mol­ecule is built up from two fused seven-membered rings and an additional three-membered ring. In both mol­ecules, one of the seven-membered rings has a chair conformation, whereas the other displays a screw-boat conformation.
