OXIDATION OF AMINES TO CARBONYL COMPOUNDS BY PYRIMIDO(4,5-B)QUINOLINE-2,4(3H,10H)-DIONE (5-DEAZAFLAVIN)

Pyrimido[4,5-b]quinoline-2,4(3H,10H)-dione (5-deazaflavin) oxidized amines under aqueous conditions to give the corresponding carbonyl compounds. This 5-deazaflavin-dependent oxidation of amines was automatically recycled and gave more than 100% of carbonyl compounds based on the 5-deazaflavin.
