  Substituted tricyclic or tetracyclic quinoxalines, tricyclic pyridoquinoxalines and bis-quinoxalines were synthesized in high yields starting from cyclic ketones by the α-bromination of cyclic ketones with N-bromosuccinimide (NBS) followed by condensation of the resulting α-bromo ketones with 1,2-diaminobenzene, 3,4-diaminopyridine, or 3,3′-diaminobenzidine. condensation - halogenation - tandem reactions

  While elemental sulfur has been largely used as oxidant or sulfurating agent, its role as a catalyst has not been developed. We report here its catalytic activity in the oxidative condensation of o-phenylenediamines with acetophenones in DMSO to provide quinoxalines. The method was also extended to α-tetralones, propiophenones (R=Me) as well as higher homologues (R=Et, n-Pr) in place of acetophenones

  虽然元素硫主要用作氧化剂或硫化剂，但其作为催化剂的作用尚未开发。我们在此报告其在邻苯二胺与苯乙酮在 DMSO中氧化缩合以提供喹喔啉的催化活性。该方法还扩展到 α-四氢萘酮、苯丙酮 (R=Me) 以及高级同系物 (R=Et, n -Pr) 以代替苯乙酮，从而产生了范围广泛的萘并喹喔啉和 3-取代的 2-芳基喹喔啉。
