synthesis of histidine‐containing peptides is not trivial due to the potential of imidazole sidechain of histidine to act as a nucleophile if unprotected. A peptide ligation method utilizing the imidazole sidechain of histidine has been developed. The key imidazolate intermediate that acts as an internal acyltransfercatalyst during ligation is generated by deprotonation. Transesterification with amino
