formation is an often encountered side reaction in the synthesis of peptide having C-terminal proline ester. A novel strategy for the avoidance of this side reaction was developed, which utilizes Pfp ester of Tsoc-amino acid and Fmoc-amino acid fluoride as the second and the third amino acid, respectively. This strategy was applied to the synthesis of 37–53 fragment of the β-chain of human chorionic gonadotropin
二酮哌啶(DKP)的形成是合成具有C末端脯氨酸酯的肽时经常遇到的副反应。开发了一种避免这种副反应的新策略,该策略利用Tsoc-氨基酸和Fmoc-氨基酸氟化物的Pfp酯分别作为第二和第三氨基酸。该策略适用于人绒毛膜促性腺激素(hCG)β链的37–53片段的合成。
