Abstract

An enantiospecific synthesis of the 5-8-5 tricyclic ring system present in the basmane diterpenes has been accomplished, starting from ethyl 3-isopropyl-2-methylene-1-methylcyclopentane-acetate readily available in five steps from (R)-limonene] employing an RCM reaction for the annulation of cyclooctane and an intramolecular rhodium carbenoid CH insertion reaction for the construction of the cyclopentane ring.
