A series of eight (-)-14-methoxymorphinan-6-ones was synthesized and biologicallyevaluated. The morphinanones 3-7 were prepared from 3-desoxy-7,8-dihydro-14-hydroxymorphinone (1). The key step in this synthetic sequence, O-methylation in position 14, was accomplished with dimethyl sulfate. Hydrolysis followed by reductive opening of the 4,5-oxygen bridge afforded the phenol 4, which was O-methylated
