Abstract The article describes an effective synthesis and chemical transformations of 6‐(morpholine‐4‐sulfonyl)‐2,3,4‐quinolinetricarboxylic acid. The key step is the Pfitzinger reaction of 3,3‐dichloro‐2‐oxo‐2,3‐dihydro‐1H‐indole with diethyl 2‐oxosuccinate. Selective 2‐decarboxylation of the tricarboxylic acid followed by reaction of the resulting anhydride with a primary amine led to the formation
摘要 本文描述了 6-(吗啉-4-磺酰基)-2,3,4-喹啉三羧酸的有效合成和化学转化。关键步骤是 3,3-二氯-2-氧代-2,3-二氢-1H-吲哚与 2-氧代琥珀酸二乙酯的 Pfitzinger 反应。三羧酸的选择性 2-脱羧,然后所得酸酐与伯胺反应,形成 1,3-二氧代-2,3-二氢-1H-吡咯并[3,4-c]喹啉支架有趣的药理活性。
