The use of a triazene function to anchor phenylalanine to a polymeric support through its side chain is reported. To prove the usefulness of this strategy in solid-phase peptide synthesis, several bioactive peptides have been prepared including cyclic, C-modified, and protected peptides. The triazene linkage is formed by coupling the diazonium salt of Fmoc-Phe(pNH2)-OAllyl to a MBHA-polystyrene resin
据报道,使用三氮烯官能团通过其侧链将苯丙氨酸锚定在聚合物载体上。为了证明该策略在固相肽合成中的有用性,已经制备了几种生物活性肽,包括环状,C-修饰的和保护的肽。三氮烯键是通过将Fmoc-Phe(p NH 2)-O烯丙基的重氮盐与事先用异戊二酸(90%)官能化的MBHA-聚苯乙烯树脂偶联而形成的。进一步组装肽链,在DCM中使用2–5%TFA将其从树脂上裂解,并在DMF中用FeSO 4 ·7H 2 O还原所得的肽重氮盐,从而获得了所需的高纯度产品(73–94 %)。
