A process for the manufacture of optically active t-butyl-phenyl phosphinamide of Formula 1 according to the invention consists in that a racemic mixture of phosphinamide is treated with enantiomerically pure (+)-(S)-mandalic acid or enantiomerically pure (+)-(R)-2,2'-dihydroxy-1,1'-binaphthyl ((R)-BINOL) in organic solvents and the resulting crystals of the supramolecular complex whose breakdown enables the isolation of enantiomerically pure phosphinamide of Formula 1 are isolated. Optically pure phosphinamide 1 enriched with an enantiomer with an absolute configuration at the stereogenic phosphorus atom opposite with respect to the compounds used is obtained from mother liquors following an appropriate isolation procedure.
根据本发明,制造光学活性式 1 的
叔丁基苯基膦酰胺的工艺包括:在有机溶 剂中,将膦酰胺的外消旋混合物与对映体纯的(+)-(S)-曼陀罗酸或对映体纯的(+)-(R)-2、2'-二羟基-
1,1'-联萘((R)-BINOL)在有机溶剂中进行处理,并分离出所得到的超分子复合物晶体,其分解可分离出对映体纯度为 1 的膦酰胺。按照适当的分离程序,从母液中获得富含对映体的光学纯膦酰胺 1,该对映体的立体构型与所使用的化合物相反。
