Racemic phosphines are converted into enantioenriched phosphine oxides via a synthetically simple, but theoretically interesting, oxidation procedure in good enantiomeric excess (up to 80%) and excellent yields (>95%). These phosphine oxides can be oxidatively coupled to provide easy access to enantiopure DiPAMPO analogues. Particularly attractive aspects of this procedure are the operational simplicity
外消旋膦通过合成简单但理论上有趣的氧化过程以良好的对映体过量(高达 80%)和优异的产率(>95%)转化为对映体富集的氧化膦。这些氧化膦可以氧化偶联,以方便获得对映体纯的 DiPAMPO 类似物。该程序特别吸引人的方面是合成这些高价值化合物所需的操作简单和成本低。
