  A Biocatalytic Route to P-Chirogenic Compounds by Lipase-Catalyzed Desymmetrization of a Prochiral Phosphine−Borane

  摘要：

  [GRAPHICS]Available methods for synthesis of P-chirogenic compounds are limited. We set out to find biocatalytical means to introduce asymmetry in a phosphine-borane. After screening different lipases, Candida antarctica lipase B was found to give excellent results in the desymmetrization of prochiral phosphine-boranes. Both enantiomers can be obtained in up to > 98% optical purity via acetylation or hydrolysis in processes that allow recycling of the substrates.
