Incorporation of a 3-aminoazetidine (3-AAz) into peptide backbones improves head-to-tail cyclizations compared to unmodified peptides. The azetidine nitrogen can be readily functionalized using substitution or click chemistry. Crystal structure analysis reveals that a 3-AAz modified cyclic tetrapeptide adopts an uncommon all-trans conformation. The 3-AAz provides stability to protease degradation compared
