An efficient enantio- and diastereocontrolled construction of hydrophenanthrenes having either a quaternary or a tertiary benzylic stereogenic center has been developed by employing a tandem retro-aldol and intramolecular Friedel-Crafts alkylation sequence. Its application to a diastereocontrolledsynthesis of an abietane diterpenoid (+)-ferruginol has also been demonstrated.
