  • The reactions of benzofuroxan with carbonyl compounds on the surface of solid catalysts

    日期:1993.12
    The cyclocondensations of benzofuroxan 1a with carbonyl compounds were smoothly and efficiently carried out by the adsorption of the components on the surface of silica gel or a molecular sieve to form a 2,3-disubstituted quinoxaline 1,4-dioxide. When the reactions using a molecular sieve 3A (powder) were carried out at 90°, the actual reaction times were reduced to 0.5-2 hours. Although Duerckheimer
    通过将组分吸附在硅胶或分子筛的表面上以形成2,3-二取代的喹喔啉1,4-二氧化物,苯并呋喃喃1a与羰基化合物的环缩反应可以平稳有效地进行。当在90°下使用分子筛3A(粉末)进行反应时,实际反应时间减少到0.5-2小时。尽管Duerckheimer报告了当使5-甲氧基苯并呋喃1e与乙酰乙酸乙酯2j反应时仅分离出7-取代的喹喔啉1,4-二氧化物,但通过我们的方法,它仅生成了6-甲氧基异构体作为反应产物。5-羧基苯并呋喃聚糖1f不与羰基化合物反应。

  • Synthesis and antimycobacterial activity of new quinoxaline-2-carboxamide 1,4-di-N-Oxide derivatives
    作者:Belén Zarranz、Andrés Jaso、Ignacio Aldana、Antonio Monge
    DOI:10.1016/s0968-0896(03)00119-6
    日期:2003.5
    As a continuation of our research and with the aim of obtaining new antituberculosis agents which can improve the current chemotherapeutic antituberculosis treatments, new series of quinoxaline-2-carboxamide 1,4-di-N-oxide derivatives were synthesized and evaluated for in vitro antituberculosis activity against Mycobacterium tuberculosis strain H(37)Rv, using the radiometric BACTEC 460-TB methodology. Active compounds were also screened by serial dilution to assess toxicity to a VERO cell line. The results indicate that some compounds exhibited a good antituberculosis activity and the arylearboxamide analogues 3, 8, and 9 were the most active compounds (EC90/MICI). Also, the cytotoxic effects indicate that these compounds have a good Selectivity Index (SI). (C) 2003 Elsevier Science Ltd. All rights reserved.

    A highly efficient and versatile method for the synthesis of quinoxaline derivatives with two benzimidazole fragments have been developed on the basis of the ring contraction of 3-(benzimidazo-2-yl)quinoxalin-2(1H)-one with 1,2-diaminobenzene and its various types of substituted and condensed derivatives. Owing to the inter- and intramolecular processes, involving self association, proton exchange
