The Passerini reaction of α-hydrazino acids, carbonyl compounds and isocyanides yielded hydrazino depsipeptides, a new class of backbone extended peptidomimetics comprising amide bond isostere. A wide range of carbonyl and isocyano components were used along the α-hydrazino acids carrying three different Nα protecting groups.
