  Synthesis of Enantiopure P-Stereogenic Diphosphacrowns using P-Stereogenic Secondary Phosphines

  摘要：

  A new synthetic route to enantiopure P-stereogenic benzodiphosphacrowns using a P-stereogenic secondary bisphosphine as the key building block is reported. Syntheses of the enantiomer and P-stereogenic crowns with various ring structures, as well as deboranation of the crown compounds and subsequent reaction with a platinum complex, are described.

• Stereospecific Construction of a <i>trans</i>-1,4-Diphosphacyclohexane Skeleton

  日期：2008.4.1

  trans-1,4-Diphosphacyclohexanes were successfully synthesized by the stereospecific intramolecular coupling reaction of the optically active bisphosphine. This is a new route for the construction of the trans-1,4-diphosphacyclohexane skeleton. A cis isomer was also prepared along with the trans isomer from a mixture of rac- and meso-bisphosphines. The coordinated boranes were easily removed to afford

  通过旋光性双膦的立体定向分子内偶联反应成功合成了反式1,4-二磷酸环己烷。这是构建反式1，4-二磷酸环己烷骨架的新途径。还从外消旋和内消旋双膦的混合物中制备了顺式异构体和反式异构体。容易除去配位的硼烷，得到相应的1，4-二磷酸环己烷。
• Catalytic Asymmetric Deprotonation Using a Ligand Exchange Approach
  作者：Matthew J. McGrath、Peter O'Brien

  DOI：10.1021/ja056026d

  日期：2005.11.30

  A novel ligand exchange approach to catalytic asymmetric deprotonation-electrophilic trapping has been developed that uses 1.3 equiv of s-BuLi, 0.06-0.2 equiv of chiral diamine ((-)-sparteine or a (+)-sparteine surrogate), and 1.2 equiv of achiral bispidine. The methodology is illustrated with a range of examples and gives access to either enantiomer of useful chiral products in good yields using substoichiometric amounts of chiral diamines.
