ligand-free Suzuki coupling protocol to unite methyl (E)-4-bromobut-2-enoate with several arylboronic acids has been accomplished. Thus, a number of variously functionalized methyl 4-arylcrotonates have been achieved in high to excellent yields under mild conditions. This method enables the preparation of diverse aryl-substituted cores of HIV-1 protease inhibitors.
已经实现了有效的无配体Suzuki偶联方案,以将(E)-4-溴丁-2-烯酸甲酯与几种芳基硼酸结合在一起。因此,已经在温和条件下以高产率至优异产率获得了许多不同官能化的4-芳基巴豆酸甲酯。该方法使得能够制备HIV-1蛋白酶抑制剂的各种被芳基取代的核心。
