Azapeptides and a method for preparing same, wherein a substituted hydrazine is selectively reacted on an alpha -halogenohydrazide, and the halohydrate of the resulting compound ( alpha -hydrazinohydrazide) is in turn selectively reacted with a gem-dicyanoepoxide to produce a novel alpha -halogenohydrazide. Azapeptides may be produced by repeating this reaction sequence.
