resulting product (II) cyclized to give the tricyclic unsaturated ketone (III). Catalytichydrogenation of III gave the trans-octahydrophenanthrone (IV) stereo- specifically. The trans-configuration of IV has been unequivocally established by degradation to the known trans-1-oxo-8-methyl-4,5-(4'-methoxybenzo)-hydrindanae (XI). Sodium borohydridereduction of IV gave trans-1β-hydroxy-7-mehtoxy-11-methyl-1
