, p. 1559 - 1564 (2007/10/03)
4-Deoxycarbazomycin B(3) was synthesized by condensation of 4-methoxy-2,3-dimethylacetanilide (8) with bromobenzene in presence of cuprous iodide and potassium carbonate, and subsequent hydrolysis with 20% aqueous ethanolic KOH, followed by cyclisation of the resulting substituted diphenylamine (9) with palladium acetate in acetic acid.

The synthesis of 8-methoxy-3-(methoxycarbonyl)-6,7-dimethyl-2-(methylamino)quinoxaline is described.The synthesized compound appeared to be identical with the product obtained by degradation of the irradiation product of lumichrome.From this the conclusion is drawn that the irradiation product of lumichrome in water is 9-hydoxylumichrome.
