Medium‐sized rings, particularly the corresponding cyclic peptides, are challenging synthetic targets. In the present study, we report an approach to medium‐sized cyclic peptides through targeted formation and collapse of cyclol intermediates. This methodology operates on β‐amino imides derived from 2,5‐diketopiperazines and offers a straightforward transition from frequently examined scaffolds in
中型环,尤其是相应的环肽,是具有挑战性的合成靶标。在本研究中,我们报告了一种通过靶向形成和破坏环中间体而实现中等分子量环肽的方法。这种方法可用于衍生自2,5-二酮哌嗪的β-氨基酰亚胺,并提供了从药物开发中经常检查的支架到很少有人访问的中等大小环的直接过渡。
