  Kinetic Resolution of Phosphines and Phosphine Oxides with Phosphorus Stereocenters by Hydrolases

  摘要：

  Lipase from Candida rugosa (CRL) and cholesterol esterase (CE) catalyzed the enantioselective hydrolysis of pendant acetates in chiral phosphines and phosphine oxides. The enantioselectivity for most substrates was modest (E = 1.5-4.8), but both hydrolases showed high enantioselectivity for one substrate, ArPhMeP=O (Ar = 1-(2-acetoxy)naphthyl, 4c), E = 81 (CRL) and 32 (GE). Preparative-scale resolution of (+/-)-4c (1.0 g) catalyzed by CRL yielded enantiomerically-enriched starting acetate, (S)-(+)-4c, 0.48 g, 90% ee as well as product alcohol, (R)(-)-4b (Ar = 1-(2-hydroxy)naphthyl), 0.39 g, 88% se. Recrystallization of 4b from toluene raised the enantiomeric purity to >95% ee. Standard chemical steps followed by stereospecific reduction gave both enantiomers of phosphine ArPhMeP (Ar = 1-(2-methoxy)naphthyl) with 96-97% ee. This phosphine is an analog of PAMP (Ar = 2-methoxyphenyl), a chiral phosphine used in asymmetric synthesis.

  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。
