title: 2α,8α-Diacet-oxy-cis-himachalane.
abstract: The title compound, C(19)H(32)O(4), was synthesized from γ-himachalene, wich was isolated from 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 screw-boat conformation, whereas the seven-membered ring displays a half-chair conformation; the dihedral angle between the mean planes of the rings is 61.99 (6)°.
