An efficient and environmentally-friendly protocol for the synthesis of 2- (arylamino) thiazoles has been investigated. The two-step, three-component reaction of aryl ketones, Nbromosuccinimide, and thiourea derivatives was performed using [bmim][BF4] ionic liquid as a solvent in one pot and gave products in good to excellent yields. Furthermore, the ionic liquid could be reused up to the 5th time
已经研究了一种用于合成 2-(芳基氨基)噻唑的高效且环保的方案。芳基酮、溴代琥珀酰亚胺和硫脲衍生物的两步三组分反应使用[bmim][BF4]离子液体作为溶剂在一锅中进行,并以良好至优异的收率得到产物。此外,离子液体可重复使用至第 5 次,而反应产率没有显着降低。在温和条件(环境温度和相对较短的反应时间)下,以高产率(78-89%)获得了十三种噻唑,并通过 NMR 数据证实了它们的结构。
