As part of our program on valorisation of moroccan essential oils, we have synthesized, from cis- and trans-himachalenes extracted from cedrus Atlantica, mono and diepoxides in 2,3 and 7,13 or 7,8 position whose configurations were established.

The stereochemistry of the major isomer, C(15)H(2)4O(2), resulting from the epoxidation of gamma-trans-himachalene has been established and hence the configurations of the resulting derivatives have been deduced. The seven-membered ring is chair shaped while the six-membered ring adopts a 1,2-diplanar conformation.
