Synthesis and Determination of 10-Oxomorphine, a Decomposition Product of Morphine

Proska, B.

, p. 687 - 688 (2007/10/02)

10-Oxomorphine, a decomposition product of morphine, was synthesized from 6-O-acetylcodeine, which was oxidized with chromic acid to 6-O-acetyl-10-hydroxycodeine.This substance was then oxidized with manganese dioxide to 6-O-acetyl-10-oxocodeine, which on hydrolysis and O-demethylation gave 10-oxomorphine.UV-, fluorimetric spectrometry, TLC and HPLC methods were used for determination of 10-oxomorphine.
