Abstract Investigation of Lactarius scrobiculatus gave two new lactarane lactones, an 8-norlactarane sesquiterpene, which is the first representative of such a class of compounds, and 4- epi -furandiol. A possible biosynthetic mechanism for the formation of these sesquiterpenes is proposed.

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.
