N-substituted-14-hydroxy-3-substituted-morphinan derivatives have been found to possess potent narcotic agonist or antagonist activity. In particular, the compound N-Cyclobutylmethyl-3,14-dihydroxymorphinan has been found to possess potent agonist/antagonist activity as a non-narcotic analgesic. A new and efficient total synthesis of these compounds is described herein from the starting material 2-(p-methoxybenzyl)-1,2,3,4,5,6,7,8-octahydroisoquinoline.
