A general Cu-catalyzed, regioselective method for the N-3-arylation of hydantoins is described. The protocol utilizes aryl(trimethoxyphenyl)iodonium tosylate as the arylating agent in the presence of triethylamine and a catalytic amount of a simple Cu-salt. The method is compatible with structurally diverse hydantoins and operates well with neutral aryl groups or aryl groups bearing weakly donating/withdrawing
描述了用于乙内酰脲的N -3-芳基化的一般的Cu催化的区域选择性方法。该方案在三乙胺和催化量的简单铜盐存在下,将甲苯磺酸芳基(三甲氧基苯基)碘鎓用作芳基化剂。该方法与结构上不同的乙内酰脲兼容,并且可以与中性芳基或带有弱供电子/吸出元素的芳基一起很好地操作。它也适用于药学上相关的乙内酰脲的快速多样化。
