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.
本发明提供了一种合成N-去甲基化N-甲基吗啡酮的方法。具体地,本发明提供了改进的合成方法,用于制备N-去甲基化吗啡酮化合物,这些化合物可以作为起始物质,例如,常见的N-甲基阿片类药物,如奥利帕汀和鸦片碱,以及奥利帕汀的C(3)-保护羟基衍生物。
