phenylalanine boronates were prepared by solid-phase Miyaura borylation of 4-iodophenylalanine peptides. Subsequent arylation through a Suzuki-Miyaura cross-coupling was carried out using a variety of aryl halides under conventional heating and under microwave irradiation. Microwaves greatly enhanced the arylation, shortening the reaction time and providing the biaryl peptides in higher purities.
树脂结合的苯丙氨酸硼酸盐是通过 4-碘苯丙氨酸肽的固相 Miyaura 硼酸化制备的。在常规加热和微波辐射下,使用各种芳基卤化物通过 Suzuki-Miyaura 交叉偶联进行随后的芳基化。微波极大地增强了芳基化,缩短了反应时间并提供了更高纯度的联芳基肽。
