Activating an inactive bond: A new concept in synthetic peptide chemistry, backbone amide activation, proceeds through the selective conversion of a backbone amide into an imide, followed by nucleophilic acyl displacement (see scheme; Boc=tert‐butoxycarbonyl, Pg=protecting group). This methodology represents a new approach to solid‐phase synthesis of C‐terminal peptide thioesters, and may become a
激活无活性键:合成肽化学中的一个新概念,即主链酰胺活化,是通过将主链酰胺选择性转化为酰亚胺,然后进行亲核酰基取代而进行的(参见方案; Boc =叔丁氧羰基,Pg =保护基) 。这种方法学代表了一种固相合成C末端肽硫代酸酯的新方法,并且可能成为合成肽硫代酸酯的通用工具。
