benzimidazole-2-carboxamide as was previously reported. The structure of the obtained quinoxaline has been confirmed by X-ray. The anti-tumor activity of synthesized quinoxalines 1–21 has been evaluated by studying their possible inhibitory effects on Epstein–Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA). Among the studied compounds 1–21, compounds 12, 8,

pyrolysis of the pyruvate hydrazones derived of the quinoxalin-4-ones at −230° to give the as-triazino[4,3-a]quinoxalin-5-ones, 4. The reaction of 5 with acetylacetone afforded 3-(3′,5′-dimethylpyrazol-1-yl)-2(1H)-quinoxalinone, 10. The structural assignments for the new compounds were based on their elemental analysis and spectroscopic data as well as an independent synthesis.

one-pot two-step synthesis of substituted-triazolo[4,3-a]quinoxalin-4(5H)-one has been developed. The 3-hydrazineylquinoxalin-2(1H)-one reacts with respective aldehyde to afford the individual hydrazineylidene intermediate which undergoes oxidative cyclization in the presence of ferric chloride hexahydrate (FeCl3.6H2O) to affords various substituted- triazolo[4,3-a]quinoxalin-4(5H)-one in good to excellent
摘要 已开发出一种有效的一锅两步合成取代三唑并[4,3 - a ]quinoxalin-4(5H)-one。3-肼基喹喔啉-2(1H)-one 与相应的醛反应生成单独的肼基中间体,该中间体在六水合氯化铁 (FeCl 3 .6H 2 O)的存在下进行氧化环化,生成各种取代的三唑并 [4,3 - a ]quinoxalin-4(5H)-一种具有良好到极好的产率。
