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).
