and coupling of the dimethylphosphinothioic mixed anhydrides of protected amino acids can be performed in alcohol solvents. Sparingly soluble protected C-terminal segments of vasoactive intestinal peptide (VIP) up to the heptapeptide stage were synthesized by this technique and fully characterized.
受保护氨基酸的二甲基硫代膦酸混合酸酐的形成和偶联可以在醇溶剂中进行。通过该技术合成了直至七肽阶段的血管活性肠肽 (VIP) 的微溶保护 C 末端片段,并对其进行了充分表征。
