enantioseparation of dialkyl‐arylphosphine oxides was elaborated, and five phosphine oxides were prepared with ee higher than 94 %. It was shown that these resolutions can be performed on gram scale, and can give both enantiomers of a phosphine oxide. It was demonstrated that organic solvent nanofiltration can serve as an alternative method of column chromatography for the recovery of the P‐oxide enantiomers and
详细说明了二烷基-芳基膦氧化物的对映体分离,并制备了五种膦氧化物,其ee高于94%。已证明这些拆分可以以克为单位进行,并且可以给出氧化膦的两种对映异构体。结果表明,有机溶剂纳滤可以作为柱色谱的另一种方法,用于回收P-氧化物对映异构体和分离剂。
