, (2008/06/13)
There is provided a novel, high yield, method of dealkylating N-alkylated 14-hydroxymorphinans and derivatives thereof including, inter alia, oxymorphone and oycodone. There are thus provided, inter alia, more efficient routes for the formation of naloxone, naltrexone, and nalbuphine. In the principal step of the process, the dealkylation using certain oxycarbonyl halides (or haloformates) is carried out on the N-alkyl-14-acyloxy-morphinan which it is desired to dealkylate.
