Inventor
Oripavine is an opiate and the major metabolite of thebaine. It is the parent compound from which a series of semi-synthetic opioids are derived, which includes the compounds etorphine and buprenorphine. Although its analgesic potency is comparable to morphine, it is not used clinically due to its severe toxicity and low therapeutic index. Due to its use in manufacture of strong opioids, oripavine is a controlled substance in some jurisdictions.
N-demethylation of N-methyl morphinans
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.
Owner:SPECGX LLC
Use of Oripavine as a Starting Material For Buprenorphine
There is provided a method for the synthesis of norbuprenorphine, and ultimately buprenorphine, utilizing oripavine as the starting material. Conventional methods of producing buprenorphine utilize thebaine as the starting material, requiring an O-demethylation step, typically a low to moderate yield transformation. The present use of oripavine as a starting material does not require an O-demethylation step, since the oripavine molecule lacks an O-3 methyl group.

Preparation of oxymorphone from oripavine
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.
