“click” approach, a model peptide was successfully modified with a diverse range of alkyl and aryl thiols. Furthermore, this technique was demonstrated as a valuable tool to induce spontaneous intramolecular cyclisation by preparation of an oxytocin analogue, in which the native disulfide bridge was replaced with a vinyl sulfide moiety formed by thia‐Michael addition of a cysteine thiol to the allenamide

化学选择性分子间或分子内桥连反应提供了一种通用的
化学工具。桥接反应具有
生物相容性,在无催化剂的
水性介质中于pH 7.4时自发发生。通过这种“点击”方法,模型肽成功地被各种烷基和芳基
硫醇修饰。此外,该技术被证明是通过制备
催产素类似物来诱导自发分子内环化的有价值的工具,
