A method of preparing oxycodone includes forming 14-hydroxycodeine by reduction of 14-hydroxycodeinone and rearrangement of the 14-hydroxycodeine to form the oxycodone. During the reduction step, the ketone group of an undesirable contaminant precursor, 8, 14-dihydroxy-7,8-dihydrocodeinone, is reduced to a hydroxyl group thus forming a triol. This triol is substantially inert with respect to reforming 14- hydroxycodeinone and can be readily separated from oxycodone.

14-羟基可待因,以及通过重排
14-羟基可待因形成
羟考酮。在还原步骤中,一种不良杂质前体8,14-二羟基-7,8-
二氢可待因酮的酮基被还原为羟基,从而形成三醇。这种三醇与再形成
14-羟基可待因基本惰性,并且可以很容易地与
