A synthesis of the ring system of terpestacin

The ring system of the sesterterpene terpestacin has been obtained from a cyclopentanic precursor prepared from endo-3-bromocamphor and from an acyclic keto phosphonate prepared from 6-methylhept-5-en-2-one. The connection of both compounds has been achieved by a Horner-Wadsworth-Emmons reaction on the one hand and by a McMurry reaction on the other.
