The dolabellanediterpene (+/-)-acetoxyodontoschismenol has been synthesised for the first time by a short route in which a three component coupling on zirconium is used to assemble all the carbons needed for the skeleton in onepot.

Terminally functionized terpenoids of the bis-norfarnesane series, stereoisomeric with respect to the centra double bond, were synthesized on the basis of 1,4-butynediol. Their electrophilic cyclization under the action of the complex Hg(OSO2CF3)2 . PhNMe2 led to a moderate yield of a mixture of monocyclic olefins.
