procedure for peptide‐bond formation is reported. Instead of activation of the carboxylic acid functionality, the reaction involves an unprecedented use of activated α‐aminoesters. The method provides a straightforward entry to dipeptides and was effective when a sensitive cysteine residue was used, as no epimerization was detected in this case. The applicability of this method to iterative peptide synthesis
报道了一种温和,实用和简单的肽键形成步骤。除了活化羧酸官能团之外,该反应还涉及前所未有的活化α-氨基酯的使用。该方法提供了直接进入二肽的方法,并且在使用敏感的半胱氨酸残基时有效,因为在这种情况下未检测到差向异构。通过在具有挑战性的N→C方向上合成模型四肽,说明了该方法在迭代肽合成中的适用性。
