Synthesis and an attempt at electrophilic cyclization of some derivatives of 2,10-dimethylundeca-1,5,9-triene

Abstract

Terminally functionized terpenoids of the bis-norfarnesane series, stereoisomeric with respect to the central 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.
