Conjugation of 4,5-Epoxymorphinan-6-ols with Bromoglucuronides in the presence of Zinc containing compounds as activator under conditions capable of forming 4,5-Epoxymorphinan-6-oxyglucuronides is disclosed. This novel approach provides an efficient method for preparation of both anomers of 4,5-Epoxymorphinan-6-oxyglucuronides. The deprotected end products are useful as analgesic agents.
