  摘要：

  The 1-alkyl-3-methyl-4-oxo-1,4-dihydropyridazino[3,4-b]quinoxalines (10a-d) were synthesized from the quinoxaline N-oxides (8a-d) via the oxidation of the 4-acetyl-1-alkyl-3-methyl-1,5-dihydropyridazino[3,4-b]quinoxalines (9a-d) with N-bromosuccinimide/water, sodium bromate, or selenium dioxide, while the 1-alkyl-3-ethyl-4-oxo-1,4-dihydropyridazino [3,4-b]quinoxalines (13a-d) were synthesized from the quinoxaline N-oxides (8a-d) via the oxidative ring transformation of the 1-alkyl-3-ethyl-2,3-dihydro-4-hydroxy-1H-1,2-diaz-epino[3,4-b]quinoxalines (12a-d), respectively.
