    Description / Table of Contents: Terpenes and Terpene Derivatives, XVII.  -  Thermal and AlCl3-Catalyzed Reaction of OcimenoneBis(trans-ocimenone) (5), reported to be a naturally occurring compound, is formed by thermal dimerization of (E)-ocimenone (E-4).  -  Treatment of 4 with AlCl3 leads, in addition to unchanged 4, to a mixture of the rearranged products filifolone (6) and rac-isopiperitenone (7). This reaction is not suitable for the synthesis of 6 on gram-scale.
    Notes: Bis(trans-ocimenon) (5), über dessen auch natürliches Vorkommen berichtet wurde, entsteht durch thermische Dimerisierung von (E)-Ocimenon (E-4).  -  Behandlung von 4 mit AlCl3 ergibt neben unverändertem 4 ein Gemisch der Umlagerungsprodukte Filifolon (6) und rac-Isopiperitenon (7). Zur präparativen Darstellung von 6 ist diese Reaktion nicht geeignet.
