Crystal structure of (1S,3R,8R,9S,10R)-10-bromo-methyl-2,2-di-chloro-9,10-ep-oxy-3,7,7-tri-methyl-tri-cyclo-[6.4.0.0(1,3)]dodeca-ne.


ABSTRACT: The title compound, C16H23BrCl2O, was synthesized in three steps 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 two fused six- and seven-membered rings, each linked to a three-membered ring. The six-membered ring has a screw-boat conformation, whereas the seven-membered ring displays a twist-boat conformation. The absolute structure was established unambiguously from anomalous dispersion effects.
