Chromatographic separation and spectrometric identification of the oxidation products from a tetrahydro-isoquinoline alkaloid.
The oxidation chemistry of 3',4'-deoxynorlaudanosoline carboxylic acid, a tetrahydroisoquinoline alkaloid, has been studied by electrochemical approaches. Four reaction products were isolated by semi-preparative high performance liquid chromatography and identified structurally by nuclear magnetic resonance, mass spectrometry, ultraviolet-visible spectrophotometry and electrochemistry studies. An oxidation mechanism was proposed.
