trifluoromethanesulfonate, and glacial acetic acid selectively catalyzed the synthesis of dihydroquinoline via Friedländer annulation. The synthesized dihydroquinoline analogues coupled with different amines by the use of coupling reagent gave dihydroquinoline carboxamide derivatives in moderate to good yields. All the synthesized novel compounds were evaluated for the anti-tubercular activity and cytotoxic
三氟甲磺酸钠和冰醋酸通过Friedländer环空法选择性催化二氢喹啉的合成。通过使用偶联剂,将合成的二氢喹啉类似物与不同的胺偶联,以中等至良好的产率得到了二氢喹啉羧酰胺衍生物。评价所有合成的新化合物的体外抗结核活性和细胞毒性活性。在测试的30种化合物中,两种化合物8g和8h对结核分枝杆菌H37Rv的MIC值分别为0.39和0.78μg/ mL,并且发现它们是无毒的。此外,当使用硅胶进行研究时,这两种化合物还显示出良好的药理特性和口服吸收 楷模。
