摘要：

The stereochemistry of the minor isomer, 3,4:9,9a-diepoxy-3,5,5,9-tetramethyldecahydro-1H-benzocycloheptene, C15H24O2, resulting from the epoxidation of beta-himachalene has been established. The atoms C10 and the gem-dimethyl groups C14 and C15 adopt two positions leading to two conformations for the seven-membered ring, boat-shaped (occupation factor 70%) and chair-shaped (30%). Modelling of these conformations agrees with the statistical distribution in the crystal.
