An electrochemical method has been developed to achieve arylation of electron-deficientarenes through reductive activation. Various electron-deficientarenes and aryldiazonium tetrafluoroborates are amenable to this transformation within the conditions of an undivided cell, providing the desired products in up to 92 % yield. Instead of preparing diazonium reagents, these reactions can begin from anilines

A visible‐light induced radical reaction of vinyl azides and α‐carbonyl benzyl bromides was developed, which provides an efficient route to polysubstituted quinolines via a CC and CN bond formation sequence.
Three-component reactions of ethyl/methyl lactate, anilines and aldehydes providing quinolines have been developed via simple iron(III) chloride catalysis without using an additional organic medium or external oxidant. This three-component protocol shows high efficiency and broad substrate tolerance, allowing quick access to diverse quinoline products under neat reaction conditions. The results reported

This disclosure features optically active stereoisomers of (2-(4-methoxy)quinolin-4-yl)(piperidin-2-yl)methanol that reduce drug resistance, compositions containing the same, and methods of using and preparing the same.
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。
