The cleavage of amide bonds under mild acidic conditions is a rare chemical event. N-Acetamide bond of peptides is extremely stable even under the strongest organic acid trifluoromethanesulfonic acid. This report mechanistically describes a new cleavable amide bond in 4-aminopyrazolyloxy acetamide peptide analogues under mild acidic conditions such as trifluoroacetic acid (10–20%) or HCl (0.1–4.0 N)

multicomponent approach enabling the installation of turn-inducing moieties that facilitate the macrocyclization of short and medium-size oligopeptides is described. The strategy comprises the Ugi ligation of peptide carboxylic acids and isocyanopeptides in the presence of aldehydes and acid or photolabile amines followed by cyclization and cleavage of the backbone N-substituents to render canonical
