Significantly improved reaction conditions for the synthesis of oxycodone (1), via the conventional two-step process involving oxidation of.

For the reduction step, aqueous acetic acid has typically been employed as the solvent. In the latter case, a high overall yield was achieved by starting from N -nororipavine ( 10 ), without the need to employ protecting groups. Employing the hydrochloride salt of thebaine ( 3 ) in the oxidation step, in place of the more traditionally used free base form of this opiate, now provides 5 in high yield and purity. Instead, using 5% Pd/BaSO 4 as the catalyst and MeOH as the solvent compley eliminated the formation of 16, giving oxycodone ( 1 ) in high yield and purity, without the need to purify the intermediates. Significantly improved reaction conditions for the synthesis of oxycodone ( 1 ), via the conventional two-step process involving oxidation of thebaine ( 3 ) into 14-hydroxycodeinone ( 5 ) and the subsequent reduction of 5 via catalytic hydrogenation, are reported. However, this was found to generate varying amounts of 14-hydroxydihydrocodeine ( 16 ) as the dominant by-product. These improved conditions have also proved effective in the synthesis of other 14-hydroxyopiates, such as oxymorphone ( 2 ) and N -noroxymorphone ( 9 ).
