Studies on cytochrome c. Part II. Synthesis of the protected heptapeptide (sequence 17–23) of Baker's yeast iso‐1‐cytochrome c

Synthesis is described for the N‐o‐nitrophenylsulfenylheptapeptide tert‐butoxycarbonylhydrazide corresponding to positions 17–23 of the amino acid sequence of baker's yeast iso‐1‐cytochrome c. Moreover a new method of selective removal of the S‐acetamidomethyl group for analytical and preparative purpose is reported.
