应用领域

简介2-苄基-4,4,5,5-四甲基-1,3,2-二杂氧戊硼烷是一种硼酯化合物。硼酯化合物是很多天然产物、药物分子的合成中间体,同时也是Suzuki -Miyaura偶联反应的基本反应物。

制备方法 · 1 条

制备将化合物苄溴(2g,11.7mmol)溶于无水DMF(40mL)中,加入联硼酸频哪醇酯(4.45g,17.5mmol),溴化亚铜(340mg,2.3mmol)以及叔丁醇钠(1.69g,17.5mmol)后,用氩气交换反应瓶中的空气进行保护,于80℃反应10小时。将反应冷却至室温,过滤除去不溶物,以少量乙酸乙酯洗涤滤饼,合并滤液,加入适量水后以乙酸乙酯萃取。收集有机层以无水硫酸钠干燥,减压浓缩后以硅胶柱层析纯化(洗脱剂为PE/EtOAc=40:1)得到产品无色油状物1.78克,收率70%。
