We have established an efficient method for preparing methyl bis(2,2,2-trifluoroethoxy)bromophosphonoacetate, which we developed for the stereoselective synthesis of (E)-α-bromoacrylates. This improved method enables the reagent to be prepared reproducibly in one step from methyl bis(2,2,2-trifluoroethoxy)phosphonoacetate.
我们已经建立了制备双(2,2,2-三氟乙氧基)溴代膦酰基乙酸甲酯的有效方法,该方法是我们为立体选择性合成(E)-α-溴代丙烯酸酯开发的。这种改进的方法使该试剂可以一步一步地由双(2,2,2-三氟乙氧基)膦酰基乙酸甲酯制备。
