Reaction of bis(2-sulfanylethyl)amido (SEA) peptides with triisopropylsilylthiol in water at neutral pH yields peptide thiocarboxylates. An alkylthioester derived from β-alanine was used to trap the released bis(2-sulfanylethyl)amine and displace the equilibrium toward the peptide thiocarboxylate.
双(2-巯基乙基)酰胺(SEA)肽与三异丙基硫醇在中性 pH 的水中反应生成肽硫羧酸酯。使用衍生自β-丙氨酸的烷基硫酯来捕获释放的双(2-巯基乙基)胺,并使平衡向肽硫羧酸酯方向移动。
