dehydrodipeptides are convenient starting materials for atom-efficient synthesis of different compounds. A one-pot ring-opening/alcoholysis/hydrolysis process with 3-nitroarylmethylene-2,5-piperazinediones yielded N-3-nitroarylpyruvoylamino esters, which gave the corresponding amines by reduction of the nitro group. In the case of 2-nitroaryl compounds, an intramolecular reductive amination afforded
