• Enantioselective Allylic C−H Oxidation of Terminal Olefins to Isochromans by Palladium(II)/Chiral Sulfoxide Catalysis
  作者：Stephen E. Ammann、Wei Liu、M. Christina White

  日期：2016.8.8

  The enantioselective synthesis of isochroman motifs has been accomplished by palladium(II)‐catalyzed allylic C−H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide‐oxazoline (ArSOX) ligand. The allylic C−H oxidation reaction proceeds with the broadest scope and highest levels of asymmetric induction reported
