Azorellanol: A diterpenoid with a new carbon skeleton from Azorella compacta

Azorellanol: A diterpenoid with a new carbon skeleton from Azorella compacta - Tetrahedron, 54(51), p.15533-15540, 1998 .

A new diterpenoid, azorellanol (5), was isolated from the whole plant of Azorella compacta (Umbelliferae). The structure was established by using mainly one- and two-dimensional NMR techniques, whereas the absolute stereochemistry was determined by X-ray diffraction analysis. The diterpenoid (5)possesses a novel hydrocarbon skeleton for which we suggest the name azorellane
