for transamidation of thioamides by N−C(S) transacylation is reported. This process exploits the concept of site-selective N-tert-butoxycarbonyl activation, resulting in ground-state-destabilization of thioamides. The study establishes a powerful direction to the development of new molecules in chemistry and biology by rational modification of nN→π*C=S resonance of the thioamide bond.
报道了第一种通过 NC(S) 转酰基作用对硫代酰胺进行转酰胺基作用的通用、温和且高度化学选择性的方法。该过程利用了位点选择性 N-叔丁氧羰基活化的概念,导致硫代酰胺的基态不稳定。该研究通过对硫代酰胺键的n N →π* C=S共振进行合理修饰,为化学和生物学新分子的发展奠定了有力的方向。
