with a range of unprotected side chains of amino acid. The ability to produce amide or peptides by a traceless removal of the auxiliary is a significant virtue of the method. Meanwhile, the application of this new peptide-bond-forming reaction to the synthesis of novel endomorphin (EM) derivatives with various binding potencies was realized.
已经设计出一种新颖且无痕的策略,其允许将硫代酸和二硫代氨基甲酸酯末端的胺偶联。在较早的天然化学连接方法中,已假定该策略取决于半胱氨酸侧链功能等同物的附着。这种方法能够无痕地去除CS 2以直接生成所需的酰胺键,并且与一系列未保护的氨基酸侧链兼容。通过无痕去除助剂产生酰胺或肽的能力是该方法的重要优点。同时,实现了这种新的肽键形成反应在具有各种结合力的新型内啡肽(EM)衍生物的合成中的应用。
