site-selective pathways to construct 4- and 5-hydroxyalkyl-substituted imidazoles through a three-component reaction of amidines, ynals, and water has been documented. Particularly, the high regioselectivity of the reaction was simply switched by changing the additives. In addition, further 18O-labeled experiments to probe a plausible mechanism and the gram-scale synthesis were studied.
通过am,乙醛和水的三组分反应来构建4-和5-羟烷基取代的咪唑的可控位点选择性途径的第一个实例已有文献报道。特别地,通过改变添加剂,可以简单地切换反应的高区域选择性。此外,还研究了18个O标记的实验,以探讨可能的机理和克级合成。
