Substituted morphinans and the use thereof

摘要

The application is directed to compounds of Formula I:;
and pharmaceutically acceptable salts and solvates thereof, wherein R1, R2, R3, R4a, and R4b are defined as set forth in the specification. The invention is also directed to use of compounds of Formula I to treat disorders responsive to the modulation of one or more opioid receptors, or as synthetic intermediates. Certain compounds of the present invention are especially useful for treating pain.
