AUTORECYCLING OXIDATION OF AMINES TO CARBONYL COMPOUNDS CATALYZED BY 3,4-DISUBSTITUTED 4-DEAZATOXOFLAVIN DERIVATIVES

3,4-Disubstituted 4-deazatoxoflavin derivatives (II) were prepared by the condensation of 6-(1-methylhydrazino)uracils (I) with appropriate α-diketones. The compounds II oxidized long-chain alkylamines such as n-octylamine and n-dodecylamine besides benzylamine and cyclohexylamine to yield the corresponding carbonyl compounds via imines, catalytically with a markedly high turnover number.
