  A Novel Resolution Procedure for the Preparation of P-Stereogenic Phosphine Oxides

  摘要：

  [GRAPHICS]A new general route for preparing enantiomerically pure P-stereogenic phosphine oxides has been developed by exploiting the Staudinger reaction between racemic tertiary phosphines and an enantiomerically pure organoazide. The resulting phosphinimines are easily resolved by either crystallization or flash chromatography and serve as synthetic intermediates toward enantiomerically pure phosphine oxides.

  摘要：

  通过利用（+/-）膦与对映纯（1S，2R）-O-（叔丁基二甲基甲硅烷基）异冰片基-10的Staudinger反应可实现多种（+/-）-P-立体异构膦的拆分-磺酰叠氮化物。非对映体膦亚胺的所得混合物通常可通过分步结晶或快速色谱分离。随后的酸催化的水解以高收率提供了相应的光学纯的氧化膦。

  (+/-)-P-stereogenic phosphines is achieved by exploiting the Staudinger reaction of a (+/-)-phosphine with enantiopure (1S,2R)-O-(tert-butyldimethylsilyl)isobornyl-10-sulfonyl azide. The resulting mixtures of diastereomeric phosphinimines are generally separable by fractional crystallization or flash chromatography. Subsequent acid-catalyzed hydrolysis provides the corresponding optically pure phosphine oxides
