Electrospray ionization mass spectrometry in the heterogeneous catalyzed organic reactions: unknown compounds in the pyruvate hydrogenation
The transformation of cinchonidine was studied in the presence of hydrogen on Pt/alumina by electrospray ionization mass spectrometry using in-source CID. So far unknown compounds were identified. Further studies on the basis of these new observations may permit to establish a more comprehensive mechanism of enantioselective hydrogenation of alpha-ketoesters.
