isolated yields was achieved. Both pinacol boronates were tested in a series of cross‐coupling reactions under Suzuki–Miyaura cross‐coupling conditions to obtain the corresponding aryl, heteroaryl, and alkenyl derivatives in high isolated yields. This methodology was applied to the formal synthesis of the glucopyranoside moiety of papulacandin D and the first total synthesis of bergenin.
一种方便的合成途径使d -glucal和d -galactal频哪醇硼酸酯,以良好的产率分离出来制备达到了。两种频哪醇硼酸酯都在Suzuki–Miyaura交叉偶联条件下进行了一系列交叉偶联反应测试,从而以高分离产率获得了相应的芳基,杂芳基和烯基衍生物。该方法学适用于木瓜素D的吡喃葡萄糖苷部分的正式合成和佛手素的首次全合成。
