Some chromeno[4,3‐b]quinolines 4a–i were obtained from β‐chloro carboxyaldehydes 3a–c with different aniline derivatives namely, aniline, 4‐fluoroaniline, and 2‐aminophenol. Surprisingly, 3a–c reacted with 2‐aminothiophenol and afforded the chromeno[3,4‐c]quinoline derivatives 5a–c. Single‐crystal X‐ray diffraction studies of 4e and 5b provided good support for the established structure. Compounds
一些色诺 [4,3 - b] 喹啉 4a - i 是从 β - 氯甲醛 3a - c 与不同的苯胺衍生物即苯胺、4 - 氟苯胺和 2 - 氨基苯酚获得的。令人惊讶的是,3a-c 与 2-氨基苯硫酚反应得到色基 [3,4-c] 喹啉衍生物 5a-c。4e 和 5b 的单晶 X 射线衍射研究为已建立的结构提供了良好的支持。与吲哚美辛相比,化合物 4b 和 5b 显示出显着的抗炎和致溃疡评分活性。
