was effectively prepared by a multicomponent reaction, employing aminomethanesulfonic acid, glyoxal, and formaldehyde. The catalytic activity of bsmim was tested in the synthesis of quinoline derivatives, by means of the Friedländer reaction, and in the allylic substitution of alcohols with nitrogen-containing heterocycles. The performance of sulfo-imidazole derivative (bsmim) resulted in higher comparison
使用氨基甲磺酸、乙二醛和甲醛,通过多组分反应有效制备了 1,3-双(磺甲基)咪唑 (bsmim)。bsmim 的催化活性通过 Friedländer 反应在喹啉衍生物的合成中以及在醇与含氮杂环的烯丙基取代中进行了测试。在相同反应条件下,磺基咪唑衍生物 (bsmim) 的性能优于羧基咪唑类似物(bcmim 和 bcmimCl)。这种离子型有机固体允许在没有溶剂和温和反应条件下促进反应,从而提高有机合成过程的可持续性。
