title: (1S,2S,4R)-3,3-Dichloro-4,8,12,12-tetra-methyl-tricyclo-[5.5.0.0]dodeca-6,8-diene.
abstract: The title compound, C(16)H(22)Cl(2), a derivative of β-himachalene, was semi-synthesized from natural essential oils of Cedrus atlantica. The mol-ecule is built up from two fused six- and seven-membered rings. The six-membered ring has a perfect chair conformation, whereas the seven-membered ring displays a screw boat conformation; the dihedral angle between the rings is 46.48 (9)°.
