protecting group for peptide synthesis was demonstrated. The synthesis of the chemotactic peptide For-Met-Leu-Phe-OH as well as the synthesis of Met-enkephalin using CAM ester as carboxyl terminal protection were performed. These esters showed good stability during acidolytic removal of BOC N-protecting group, during hydrogenolysis of Z N-protecting group and during removal of FMOC N-protecting group. CAM
证明了羧酰胺基甲基酯(CAM酯)作为用于肽合成的羧基保护基的用途。进行了趋化肽For-Met-Leu-Phe-OH的合成以及使用CAM酯作为羧基末端保护的Met-脑啡肽的合成。这些酯在酸解去除BOC N-保护基期间,Z N-保护基的氢解期间和FMOC N-保护基的去除期间显示出良好的稳定性。CAM酯可被NaOH 0.5 N或Na 2 CO 3迅速裂解。但是,当序列中存在天冬氨酸的β-苄基酯时,我们未能成功地选择性除去CAM酯。
