Example 8: Epimeric Ratios and Yields[0082] Example 8 depicts the conversion of certain 6-keto morphinans (oxymorphone, noroxymorphone, oxycodone, naloxone, and naltrexone) to their corresponding 6-hydroxy morphinans. Specifically, the following table provides the epimeric ratio of 6-α-hydroxy morphinan to 6-β-hydroxy morphinan and the corresponding yields for each compound.
