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 drug discovery to a rarely visited class of medium‐sized rings.
