Guaianes and Cycloguaianes

11-Cycloguaianes are referred to as aromadendranes. Various aromadendrenes and aromadendradienes belong to the constituents of balsamum tolutanum from Myroxylon balsamum (Leguminosae). The oil of sage from Salvia sclarea (Labia-tae), cultivated for perfumery in the south of Europe, contains (+)-l(10)-aroma-dendren-7-ol also known as isospathulenol. 

Cubebanes and ivaxillaranes represent 1,6- and 8,10-cycloguaianes, respectively. The fruits of Java pepper Piper cubeba (Piperaceae) contain (-)-4-cubebanol. The name ivaxillarane stems from Iva axillaris with (-)-ivaxillarin as a constituent. 

Valerenanes is the common name of 8(7-6)-abeoguaianes, in which the seven-membered ring of guaiane has contracted to cyclohexane, involving a migration of C-8 from C-7 to C-6. Few valerenanes are known to date, including valerenol.
