Rapid synthesis of quinoline-4-carboxylic acid derivatives has been achieved by reaction of 2-methoxy acrylates or acrylamides with N-arylbenzaldimines in acetonitrile under InCl3 catalysis and microwave irradiation. Isolated yields up to 57% within 3 min have been obtained. The Lewis acid and the microwave activation appeared as crucial parameters for the reaction. The role of indium chloride and ytterbium triflate was specified using 13C NMR data and model theoretical studies.
在三氯化铟催化和微波辐射下,通过2-甲氧基丙烯酸酯或丙烯酰胺与N-芳基苯甲醛亚胺在乙腈中反应,实现了喹啉-4-羧酸衍生物的快速合成。在3分钟内获得了高达57%的分离产率。路易斯酸和微波活化是该反应的关键参数。利用13C NMR数据和模型理论研究确定了氯化铟和三氟甲磺酸镱的作用。
