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
从环酮开始,通过环酮与N-溴代琥珀酰亚胺(NBS)的α-溴化反应,然后将所得的α-溴代酮与1,2缩合,以高收率合成了取代的三环或四环喹喔啉,三环吡啶并喹喔啉和双喹喔啉。-二氨基苯,3,4-二氨基吡啶或3,3'-二氨基联苯胺。 缩合-卤化-串联反应-杂环-芳烃
