The chemical synthesis of isozizaene- and cedrene-type nor-sesquiterpenoids from a simple bio-inspired precursor nor-bisabolyl epoxide is described. This key intermediate undergoes selective cyclization cascades without the need for enzymatic control. By choosing cationic or radical cyclization conditions, each sesquiterpene scaffold could be prepared selectively and led to the discovery of new woody
