(α-Benzyloxycarbonyl-aminoacyl)benzotriazolides (Cbz = benzyloxycarbonyl) underwent a coupling reaction with α-hydrazino acids under microwave irradiation to form hybrid hydrazino dipeptides (42-71 %). Chiral acylations of β-N-Cbz-α-hydrazino acylbenzotriazolides were successfully carried out with N-, S-, O-, and C-nucleophiles in yields of 49-88 %. Benzyloxycarbonyl-protected hybrid hydrazino dipeptides and benzyloxycarbonyl-protected hydrazino aminoacyl conjugates with N-, S-, O-, and C-nucleophiles were prepared by using benzotriazole methodology.
