Cover Feature: Exploration of N‐Arylation of Backbone Amides as a Novel Tool for Conformational Modification in Peptides (Chem. Eur. J. 40/2023)

Abstract

N-aryl amide bonds for peptide conformation: In the universe of peptides,theN-aryl amide bond, with its large steric and electronic effects and ability to restrain amide bond rotation, is represented as a new star. By employing N-arylation as a backbone amide modification strategy in peptides, we could unravel the different worlds of distinct and predominantly homogeneous conformations in cyclic hexa- and cyclic pentapeptides containing one or two N-aryl amide bonds.
