Graphical Abstract

From termite soldier's secretions: The enantioselective total synthesis of the diterpene (+)-cubitene is described. The route is characterized by the cyclization of a carvone-derived C20 allylphosphate with SmI2, followed by fragmentation to the twelve-membered ring. As a result, perfect stereocontrol of the isopropenyl-substituted positions is achieved.
