The natural autoxidation of thujopsene 1 afforded three dimeric peroxides (14,15, and 16) as the major products. 9α,10-Epoxy-8α-thujopsanol 17 was separated as a minor product besides other known compounds, allylic alcohols 2 and 3, mayurone 7, thujopsane-8α,9α-diol 11, and thujopsan-9-ones 19 and 20.

The transformations of (-)-thujopsene in liquid (HSO3F-SO2FCl) and over solid (TiO2/SO42-) superacids, as well as by the action of peroxy acids, were studied. New tricyclic hydrocarbons were isolated. The experimental results were compared with the data of computer analysis of the most probable transformation pathways using molecular-mechanics and quantum-chemical methods.
