One after the other: Triblock peptide synthesis was achieved at ambient temperature by sequential reaction of sulfonamide‐protected peptidyl thioacids first with highly reactive 2,4‐dinitrobenzenesulfonamides and second with more moderately reactive sulfonamides to produce the oligopeptides in good yields. The method is compatible with C‐terminal thioesters and thus presents a new approach for native
一个接一个:三嵌段肽的合成是在环境温度下通过磺酰胺保护的肽基硫酸首先与高反应性的 2,4-二硝基苯磺酰胺,然后与反应性中等的磺酰胺顺序反应来实现的,从而以良好的收率生产寡肽。该方法与 C 端硫酯兼容,因此为天然化学连接策略提供了一种新方法。
