摘要:
The present invention is generally directed to a process for the preparation of a ketomorphinan comprising maintaining a ketone group as unprotected and performing reductive amination using a hydrogen source and a catalyst.
摘要:
The present invention provides (+)-morphinans comprising Toll-like receptor 9 (TLR9) antagonist activity, as well as methods for using the (+)-morphinans to treat pain. Also provided are pharmaceutical combination compositions comprising a (+)-morphinan and an opioid agonist/monoamine reuptake inhibitor, as well as methods for using the combination compositions to treat pain.
摘要:
The present invention is directed to the reduction of an N-imine moiety or a hemiaminal moiety of a morphinan in the presence of a ruthenium, rhodium, or iridium asymmetric catalyst and a hydrogen source.
