The cyclization of a number of functionalized polyenes with mercuric triflate - N,N-dimethylaniline complex (Nishizawa's reagent) to give bicyclic or tricyclic products has been studied. Suitably positioned internal nucleophiles, such as carbonyl, hydroxy and β-ketoester groups were found to participate to varying extent, in the termination of these cyclizations.

chlorination of polyprenoids and titanocene-mediated radicalcyclization of epoxypolyprenes. We have applied this synthetic route to the first synthesis of the diterpene, (13E)-ent-labda-8(17),13-diene-3β,15,18-triol. A stereoselective approach to this synthesis is also described. diterpene -radicalcyclizations- oxiranes -stereoselectivesynthesis- titanocene
