The known sesquiterpenes that arise biosynthetically from hedycaryol are summarised. Reasonings for the assignments of their absolute configurations are discussed. The analysis provided here suggests that reprotonations at the C1=C10 double bond of hedycaryol are directed toward C1 and generally lead to 6-6 bicyclic compounds, while reprotonations at the C4=C5 double bond occur at C4 and result in 5-7 bicyclic compounds.

Keywords: biosynthesis; configuration determination; hedycaryol; sesquiterpenes; structure elucidation.
