摘要：
The title compound, C16H22Br2Cl2, was synthesized from beta-himachalene (3,5,5,9-tetramethyl-2,4a, 5,6,7,8-hexahydro-1Hbenzocycloheptene), which was isolated from the essential oil of the Atlas cedar (Cedrus Atlantica). The molecule is built up from fused six-and seven-membered rings and an appended three-membered ring. The six-membered ring has a half-chair conformation, whereas the seven-membered ring displays a chair conformation. The dihedral angle between the two best plane through each ring is 59.5 (2)degrees. No specific intermolecular interactions were discerned in the crystal packing.
