The first enantiospecific total synthesis of the tricyclic sesquiterpene (+)-seychellene, starting from (R)-carvone via (S)-3-methylcarvone, has been accomplished employing a combination of an intermolecular Michael addition–intramolecular Michael addition sequence and an intramolecular alkylation reaction for the generation of the two vicinalquaternarycarbonatoms.

single step a homoisotwistane derivative 17, which was converted to a ketone 22. Both (±)-patchouli alcohol 1 and (±)-seychellene 2 were synthesized using reactions at the bridgehead position (C-7) of a bicyclo[3.3.1]nonan-2-one system contained in 22.
