  Preparation of Enantiopure Ketones and Alcohols Containing a Quaternary Stereocenter through Parallel Kinetic Resolution of β-Keto Nitriles

  摘要：

  Racemic 1-methyl-2-oxocycloalkanecarbonitriles have been subjected to bioreduction by the fungus Mortierella isabellina NRRL 1757 through a parallel kinetic-resolution process. The u and l alcohols thus obtained (up to >99% ee) were easily separated and oxidized to the R and S ketones, respectively. The process can be then repeated so that both enantiomers of the ketone and two epimers of the alcohol can be obtained in their enantiopure forms.

  日期：2004.4.1

  Herein, we describe the diastereoselective synthesis of five- and six-membered α,α-disubstituted cyclic β-hydroxy nitriles and their resolution via enzymatic transesterification. By this method, all possible stereoisomers were obtained in enantiopure form and high yield.

  在本文中，我们描述了五元和六元α，α-二取代的环状β-羟基腈的非对映选择性合成及其通过酶促酯交换反应的拆分。通过这种方法，以对映纯形式和高收率获得了所有可能的立体异构体。
