摘要:
An improved method for the preparation of oxymorphone from oripavine is provided. Oripavine is oxidized to form 14-hydroxymorphinone after which the oxidation reaction is quenched to prevent the formation of 1-1′-dimer side products. The 14-hydroxymorphinone is then reduced, typically by catalytic hydrogenation to form oxymorphone. The inventive method disclosed is further applicable to the production of morphinan derivatives.
