New hydrazide derivative identified as bis‐di‐N‐acylamino acid hydrazide was synthesized from N‐acylamino acid and hydrazine under papain catalysis. The reaction was carried out at pH 5.0, 38°C in a mixture containing 0.2M Z‐X‐OH + or Boc‐X‐OH, 2% NH 2 NH 2 ·H 2 O, 0.8% β‐mercaptoethanol, 0.1.% EDTA and 50 mg/ml of papain. The bis‐hydrazide can be used in peptide synthesis via oxidation.
