| titleOfInvention | Use of oripavine as a starting material for buprenorphine |
| abstract | Here, a method of synthesis of norbuprenorphine and finally buprenorphine is provided, utilizing oripavine as a starting material. Conventional methods for producing buprenorphine utilize thebaine as a starting material and require an O-demethylation step, which is typically a low to medium yield conversion. Since oripavine molecules lack the O-3 methyl group, the use of oripavine as a starting material at this time does not require an O-demethylation step. |
