Quinoline‐4‐carboxamides and 4‐carboxylates are a class of heteroaromatic compounds present in a large family of laboratory‐made molecules, with a wide range of important biological activities. Herein, a synthetic approach to its accelerated assembly is described, using a rearrangement of N‐vinylisatins, promoted by different types of amines (or ethanol) in a Pfitzinger‐like mechanism that, in turn
喹啉-4-羧酰胺和4-羧酸盐是存在于大量实验室合成分子中的一类杂芳族化合物,具有广泛的重要生物活性。本文描述了一种加速组装的合成方法,该方法使用N-乙烯基赖氨酸的重排,由不同类型的胺(或乙醇)以类似Pfitzinger的机理促进,进而建立喹啉环系统。
