A synthetic approach to the novel fomannosane sesquiterpene natural product illudosin 2 from the diquinane precursor 5, readily available in turn from commercial 1,5-cyclooctadiene, is delineated. The key steps are the stereoselective construction of the cis, anti, cistricyclo[6.2.0.0(2,6)]decane system, strategic C-C bond disengagement through Baeyer-Villiger oxidation and functional group adjustments to deliver the carbocyclic core 18 present in the natural product.
