The reaction of methyl 3-(arylamino)acrylates with hydrogen iodide gave 1,2-dihydroquinoline-3-carboxylic acid derivatives at room temperature. This reaction proceeds efficiently in alcoholic solvent; bulky tert-butyl alcohol is the best solvent to give the 1,2-dihydroquinoline derivatives. It is particularly interesting that hydrogen iodide is the most efficient acid to achieve this reaction in tert-butyl
3-(芳基氨基)丙烯酸甲酯与碘化氢的反应在室温下得到1,2-二氢喹啉-3-羧酸衍生物。该反应在醇溶剂中有效地进行。大体积的叔丁醇是产生1,2-二氢喹啉衍生物的最佳溶剂。特别有趣的是,碘化氢是在叔丁醇中完成该反应的最有效的酸。苯环上的各种取代基是适用的。带有带有给电子基团的间位取代的苯环的化合物以良好的产率产生相应的1,2-二氢喹啉衍生物。 环化-碘化氢-杂环-溶剂效应-取代基效应
