We present a concept termed “deprotective functionalization”, which we have applied to the coupling of Nms-protected amines with carboxylic acids. Notably, this approach circumvents the need for a dedicated amine-deprotection step and obviates the use of additional reagents for carboxylate activation. The reaction was shown to be, in many cases, superior to deprotection followed by functionalization
我们提出了一个称为“脱保护官能团化”的概念,我们已将其应用于 Nms 保护胺与
羧酸的偶联。值得注意的是,这种方法避免了对专用胺脱保护步骤的需求,并且避免了使用额外的
羧酸盐活化试剂。在许多情况下,该反应在产率和原子经济性方面都优于脱保护后官能团化。
