A new and metal-free three-component method for the synthesis of 2,4-disubstituted quinolines via the reactions of anilines, α-keto acids and alkyl lactates is reported. The reactions proceed in the presence of p-toluene sulfonic acid (p-TSA) and tert-butyl peroxybenzoate (TBPB) to provide diverse quinoline products via the construction of new CC double, C–C single and CN double bonds without producing
报道了一种通过苯胺、α-酮酸和乳酸烷基酯反应合成 2,4-二取代喹啉的新型无金属三组分方法。该反应在对甲苯磺酸 ( p -TSA) 和过氧苯甲酸叔丁酯 (TBPB)的存在下进行,通过构建新的 C C 双键、C-C 单键和 C N 双键来提供多种喹啉产物,而不会产生任何基于质量的有机副产品。值得注意的是,喹啉的抗炎活性已通过测量其抑制脂多糖 (LPS) 诱导的 RAW264.7 细胞释放 NO 的能力来研究,从而鉴定出4i,4t和4x作为体外有效的抗炎化合物。
