Two enantiopure fluorous phosphines have been conveniently synthesized by combining palladium-catalyzed coupling reactions of easily available binaphthyl building-blocks with the introduction of fluorous ponytails onto aromatic compounds via ether bond formation. These new fluorous chiral phosphines have been tested as ligands in metal-catalyzed asymmetric transformations, the best results being obtained
通过将钯催化的易获得的联萘基结构单元的偶联反应与氟醚马尾通过醚键形成引入芳族化合物相结合,已方便地合成了两种对映体纯的氟膦。这些新的氟手性膦已在金属催化的不对称转化中作为配体进行了测试,在钯催化的1,3-二苯基-2-丙烯乙酸酯的钯催化的不对称烯丙基取代中获得了最佳结果,提供了高达87%ee的产物
