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.
发现简单的肽苯基酯在咪唑的促进下可以顺利地与半胱氨酸进行天然化学连接。这种新的连接在空间不受阻碍和受阻的C末端位点(例如Val,Ile,Pro)均迅速进行,从而以高至优异的产量形成了所需的产物。
