Studies on cytochrome c. Part III. Synthesis of the protected heneicosapeptide (sequence 24–44) of Baker's yeast iso‐1‐cytochrome c

Syntheses are described for two N ‐benzyloxycarbonylpeptide tert ‐butoxycarbonylhydrazides which correspond to positions 24–34 and 35–44, respectively, of the primary structure of baker's yeast iso‐1‐cytochrome c. The two peptide derivatives were coupled via the azide procedure to form the N ‐benzyloxycarbonylheneicosapeptide tert ‐butoxycarbonylhydrazide (sequence 24–44).
