Abstract

The primary oxidation products of 2,3-dimethylquinoxaline with selenium dioxide are 3-methylquinoxaline-2-carbaldehyde, 1,3-dihydro-1,3-dihydroxyfuro[3,4-b]quinoxaline and quinoxaline-2-carboxylic acid. 3-Methylquinoxaline-2-carboxylic acid can be obtained in a second oxidation step only. 2,4-Dimethylquinazoline is dehydrogenated by selenium dioxide to the heterocyclic stilbene derivative 8. Confirmation of structure of 8 is given by NMR-spectroscopy. [ABSTRACT FROM AUTHOR]
