, p. 405 - 416 (2009)
An efficient method has been proposed for the preparation of a series of 3-O-acyl derivatives of naloxone. The features of the steric structure and NMR spectra are discussed. Pharmaceutical investigation has shown the promise within the synthesized compou

The invention describes the process of catalytic O-demethylation of 3-methoxy-morphinane compounds using boron tribromide. Addition of catalysts reduces the reaction time, improves reacting the substrate to give the product in very good purity and yield. The said approach can be used, for example, for the preparation of oxymorphone, naltrexone, naloxone and nalbuphine from their respective O-methyl derivatives.
