A novel class of reagents, thioester isocyanides, have been prepared and applied in the synthesis of peptide macrocycles. The isocyanide part of the molecule is deployed in a multicomponent macrocyclization step. This step is followed by chemoselective peptide ligation at the thioester part of the macrocycle. Our method can now be used for rapid assembly and evaluation of cycleâtail peptides.
一种新型试剂,硫酯异氰酸酯,已经被合成并应用于肽大环的合成。分子的异氰酸酯部分在多组分大环化步骤中被使用。此步骤之后是对大环的硫酯部分进行化学选择性肽连接。我们的方法现在可以用于快速组装和评估环-尾肽。
