A concise and efficient solid-phase synthesis of biaryl cyclic peptides containing a Phe–Tyr or a Tyr–Tyr linkage has been accomplished. The key steps include a Miyaura borylation of a resin-bound 3-iodotyrosine and a microwave-assisted Suzuki–Miyaura reaction for the formation of the macrocycle. First, the feasibility of the solid-phase Miyaura borylation of a 3-iodotyrosyltripeptide was established
已经完成了含有 Phe-Tyr 或 Tyr-Tyr 键的联芳环肽的简洁高效的固相合成。关键步骤包括树脂结合的 3-碘酪氨酸的 Miyaura 硼酸化和用于形成大环的微波辅助 Suzuki-Miyaura 反应。首先,确定了 3-碘酪基三肽的固相 Miyaura 硼酸化的可行性。然后,将 Suzuki-Miyaura 反应应用于线性 3-硼酪氨酸肽基树脂与碘苯和卤代芳香族氨基酸的交叉偶联。最后,通过制备含有所需硼酸酯和卤代衍生物的线性肽基树脂,然后进行微波辅助 Suzuki-Miyaura 大环化,将该方法扩展到联芳环肽的合成。
