The present invention provides a synthetic process for the N-demethylation of N-methyl morphinans. In particular, the invention provides improved synthetic methods for the preparation of N-demethylated morphinan compounds that may be employed as starting materials, for example, commonly available N-methyl opiates such as oripavine and thebaine, and C(3)-protected hydroxy derivatives of oripavine.

Disclosed are analgesic-related compositions and methods of using the compositions for modulation of analgesic receptor activity. The compositions and methods are useful for reducing pain, as well as for therapeutic intervention of addictions or other diseases or disorders amenable to treatment or prophylaxis by modulation of analgesic receptor signaling.
