    摘要: The present invention provides a synthetic process for the N-demethylation of N-methyl morphinans. In particular, the invention provides improved synthetic methods for the preparation of N-demethylated morphinan compounds that may be employed as starting materials, for example, commonly available N-methyl opiates such as oripavine and thebaine, and C(3)-protected hydroxy derivatives of oripavine.

    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.

    摘要: An improved opiate synthesis scheme is provided. An improvement to the oxidation of oripavine and oripavine derivatives comprises the in-situ formation of the peroxacids required to oxidize the oripavine and oripavine derivatives to form an intermediate. An improvement to the reduction of the intermediate to form oxycodone and oxycodone derivatives comprises reduction utilizing a hydrogen transfer reagent. These improvements allow the production of oxycodone and oxycodone derivatives without isolation of the intermediate, providing a one-pot synthesis method.
