The present invention relates to a method for increasing the enantiomeric excess of a chiral phosphine oxide, a chiral phosphine sulphide, a chiral phosphine-borane and a chiral phosphine imide said method comprising the steps of: (a) contacting said chiral phosphine oxide, sulphide, imide or borane with a solvent to form a slurry; (b) partitioning the phosphine oxide, sulphide, imide or borane either into the solvent or as an insoluble product; and (c) optionally, isolating the partitioned phosphine oxide, sulphide, imide or borane.
本发明涉及一种用于增加手性亚磷酰氧化物、手性亚磷酰硫、手性亚磷酰-硼烷和手性亚磷酰亚胺的对映体过量值的方法,所述方法包括以下步骤:(a)将所述手性亚磷酰氧化物、硫、亚胺或硼烷与溶剂接触以形成悬浮液;(b)将亚磷酰氧化物、硫、亚胺或硼烷分配到溶剂中或作为不溶产物;以及(c)可选地,分离出分配的亚磷酰氧化物、硫、亚胺或硼烷。
