Multicomponent synthesis of hydrazino depsipeptides

The Passerini reaction ofalpha-hydrazino acids, carbonyl compounds and isocyanides yielded hydrazino depsipeptides, a new class of backbone extended peptidomimetics comprising amide bond isoster. A wide range of carbonyl and isocyano components were used along the alpha-hydrazino acids carrying three different N alpha protecting groups. The kinetics and thermodynamic equilibrium of the rate-determining step of the reaction with different alpha-hydrazino acids were studied by DFT approach.
