An efficient and highly regioselective N-methylation of (NH)-(benz)imidazoles furnishing the sterically more hindered, less stable, and usually minor regioisomer has been developed. The methodology involves very mild reaction conditions and tolerates a wide range of functional groups.
已经开发了一种高效且高度区域选择性的(NH)-(苯并)咪唑的N-甲基化,其提供在空间上更受阻,不太稳定并且通常为较小的区域异构体。该方法涉及非常温和的反应条件,并能耐受各种官能团。
