(−)-isoledene, both easily available from (+)-aromadendrene has been investigated. Reactions at the double bond of ledene take place preferably from the β-side. Under acidic conditions its C7–C8 β-epoxide and β-diol preferably react via carbocations, which are initially formed at C8. Rearrangement takes place to compounds with cubebane and cadinane skeletons. The reaction pattern of isoledene and its α-epoxide
