AbstractThe syntheses of m‐azido‐L‐phenylalanine, p‐azido‐o‐nitro‐L‐phenylalanine, Z · Ala‐Ala‐Xxx · OH, and Z · Ala‐Ala(β‐3H)‐Xxx · OH, with Xxx – Phe, Phe(p‐NO2), Phe(p‐N3), Phe(m‐N3), and Phe(p‐N3, o‐NO2) are described. The tripeptides with substituted phenylalanine residues are reversible inhibitors of chymotrypsin in the dark, and irreversible ones in the light. Photoaffinity labelling of chymotrypsin has been reported by the authors in FEBS Letters 46, 347 (1974).
