HCID 5359420(4R,4aS,12bS)-4a-hydroxy-9-methoxy-3-methyl-2,4,7a,13-tetrahydro-1H-4,12-methanobenzofuro[3,2-e]isoquinolin-7-one

Procedure

EP 1 658 293 B (Zentiva, A.S.) discloses a method of preparation of oxycodone by reaction of thebaine with hydrogen peroxide or peroxoacids in the presence of oxalic acid and of another organic acid. To the resulting crystalline precipitate of 14-hydroxy-codeinone oxalate is added a base to form 14-hydroxycodeinone, which is hydrogenated with hydrogen in the presence of a catalyst to yield oxycodone.
