A sequential one-pot approach to 2,4,5-trisubstituted imidazoles has been developed from α-methylene ketones and aldehydes. This methodology employs air-moisture stable reaction conditions and an inexpensive iodine/DMSO system affording a diverse range of known and novel (substrate scope) 2,4,5-trisubstituted imidazoles in moderate to excellent yields. The iodine/DMSO system was extended to the domino
已开发出一种从 α-亚甲基酮和醛连续一锅法制备 2,4,5-三取代咪唑的方法。该方法采用空气-水分稳定的反应条件和廉价的碘/DMSO 系统,以中等至优异的产率提供各种已知和新型(底物范围)2,4,5-三取代咪唑。将碘/DMSO系统扩展到两种功能化中间体苯偶酰和苯甲醛的多米诺聚合合成,以产生最终产物。
