Simple phenyl esters of peptides were found to undergo native chemical ligation with cysteine smoothly under the promotion of imidazole. This new ligation proceeded rapidly at both sterically unhindered and hindered C‐terminal sites (e.g., Val, Ile, Pro) to form the desired product in good to excellent yields.
