• One-ligand Catalytic Asymmetric Deprotonation of a Phosphine Borane: Synthesis of <i>P</i>-Stereogenic Bisphosphine Ligands
  作者：Johan Granander、Francesco Secci、Steven J. Canipa、Peter O’Brien、Brian Kelly

  DOI：10.1021/jo200708e

  日期：2011.6.3

  A new protocol for the catalytic asymmetric deprotonation of a phosphine borane using s-BuLi and sub-stoichiometric quantities of chiral diamines is reported. The method involves three sequential additions of s-BuLi, and use of (-)-sparteine or the (+)-sparteine surrogate facilitates access to P-stereogenic phosphines with opposite configuration. The method is exemplified by the catalytic asymmetric synthesis of each enantiomer of precursors to QuinoxP*, trichickenfootphos, and Mini-PHOS.
