The synthesis of hydroxyelemane 5 from (R)-carvone and its utilization as a common synthetic scaffold to produce structurally diverse germacrane and guaiane sesquiterpenes are described. A highly enantio- and stereoselective biomimetic tandem oxy-Cope/ene rearrangement was used as the key reaction to access the 10-membered macrocyclic core of germacranes and the condensed 5-7 carbocycles of guaiane sesquiterpenes. Additionally, reactions of furanoguaianes under acidic or oxidizing reagents have been investigated, and preliminary results of these conversions are presented.

The absolute stereostructure of a new bioactive sesquiterpene named furanogermenone (1), which was isolated from Chinese Zedoariae Rhizoma, has been determined on the basis of chemical and physicochemical evidence.
