A base-catalyzed condensation of diacetamido sulfides [(RNHCOCH2)2S)] with glyoxal affording thiophene-2,5-dicarboxylic acid bis-aryl(alkyl)amides has been accomplished under mild conditions. Excellent results were readily obtained when R was a substituted 3-nitrophenyl, 4-nitrophenyl, 4-chlorophenyl group, but the yield was poor when R was cyclohexyl. Unknown compounds were characterized by elemental
已在温和条件下完成二乙酰氨基硫化物 [(RNHCOCH2)2S)] 与乙二醛的碱催化缩合反应,得到噻吩-2,5-二羧酸双-芳基(烷基)酰胺。当R为取代的3-硝基苯基、4-硝基苯基、4-氯苯基时容易获得优异的结果,但当R为环己基时产率较差。未知化合物通过元素分析、IR、1H 和 13C NMR 技术进行表征。© 2005 Wiley Periodicals, Inc. 杂原子化学 16:503–506, 2005; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20153
