Preparation of Saturated Ketone Morphinan Compounds Having Low Metal Content |
| abstract |
The present invention provides processes for the preparation of saturated ketone morphinan compounds from a morphinan comprising an allyl alcohol ring moiety, wherein the final product has a low metal content. In particular, the invention provides processes that utilize isomerization reactions catalyzed by transition metal catalysts and the subsequent removal of the transition metal using metal scavengers. |
