The synthesis and modification of peptides occupy a unique position in the field of drug development, and the functionalization of aminoacids is a valuable strategy as an alternative to peptide modification. Currently, the development of tyrosine (Tyr) as a target aminoacid is a major challenge in the field of chemistry. Herein, we report an electrochemical radical coupling reaction of labeling tyrosine-containing
