series of tetrasubstituted silylated pinacol vinylboronates and trisubstituted silylated vinyl MIDA-boronates was synthesized by using the boron-Wittig approach. By using this protocol, the boryl and the silyl groups can be directly and highly stereoselectively incorporated into the olefin‘s anti-position. Further, sequential Suzuki coupling of the silylated vinyl boronates allows access to several
采用硼-维蒂希法合成了一系列四取代甲硅烷基化频哪醇乙烯基硼酸酯和三取代甲硅烷基化乙烯基MIDA-硼酸酯。通过使用该方案,硼基和甲硅烷基可以直接且高度立体选择性地结合到烯烃的反位中。此外,硅烷化乙烯基硼酸酯的连续 Suzuki 偶联可以得到几种全碳四取代烯烃、抗癌药物他莫昔芬和 AIEgen 试剂 TPE-TF17。
