strategy to improve the efficiency of Suzuki coupling reactions is introduced by combining fast microwave reaction with easy fluorous separation. Aryl perfluorooctylsulfonates derived from the corresponding phenols are coupled with aryl boronic acids to form biaryls under general microwave conditions. Both intermediates and products are purified by solid-phase extraction over FluoroFlash silica gel
[反应:见正文]通过将快速微波反应与容易的荧光分离相结合,提出了一种提高铃木偶联反应效率的新策略。在常规微波条件下,将衍生自相应酚的芳基全氟辛基磺酸酯与芳基硼酸偶合形成联芳基。中间体和产物均通过在FluoroFlash硅胶上进行固相萃取来纯化。还描述了该标签策略在联芳基取代的乙内酰脲的多步合成中的应用。
