The first enantioselectivesynthesis of hushinone, a tricyclic norsesquiterpenoid with an unprecedented carbon framework identified from the essential oils of birch trees, was accomplished by using intramolecular halolactone alkylation as the key step. Two other bicyclic norsesquiterpenoids in the essential oils, birkenol and birkenal, which share the same carbon skeleton as hushinone, were also synthesized
