The present invention provides a process for preparing a saturated 6,14-dihydroxy morphinan. The process comprises contacting an unsaturated 6-O-hydrocarbyl morphinan with hydrogen peroxide and an organic acid to form an unsaturated 6-keto-14-hydroxy morphinan. The unsaturated 6-keto-14-hydroxy morphinan is contacted with a first reducing agent to form an unsaturated 6,14-dihydroxy morphinan, and the unsaturated 6,14-dihydroxy morphinan is contacted with a second reducing agent to form the saturated 6,14-dihydroxy morphinan.
trans- 10 Hydroxythebaine and (8S)-8-hydroxyoxycodone were identified as by-products of thebaine oxidation with hydrogen peroxide in acidic medium. Structures of isolated compounds were determined by spectral methods.
