Versuchsvorschrift

In the first method of this invention, codeinone is reacted with hydrogen peroxide in water in the presence of an acid at about 15° to about 70° C. for a period of time depending on the scale of the reaction to afford 14-hydroxycodeinone in good yield. 14-Hydroxycodeinone so produced is hydrogenated in the same reaction media with a catalyst to afford oxycodone in good yield. Preferably the temperature is between about 40° to about 50° C. and the acid is formic acid.
