The esterification of various sesquiterpenoid alcohols of Luctarius origin with N-benzoyl-[2R,3S]-phenylisoserine (side chain of Taxol (R)) produced compounds whose antifeedant properties against storage pests Tribolium confusum, Trogoderma granarium and Sitophylus granarius were measured. The introduction of the taxol side chain in these molecules, in comparison to original compounds, moderately enhanced their antifeedant activities, as well as changed their selectivity of activity towards the test insects.

The absoluteconfiguration of furosardonin A and secolactarane sesquiterpenes has been established by chemicalcorrelations. Secolactarane lactones and furans have been converted to lactaranes by the Me2AlCl catalyzed ene reaction.
