  One-Pot Sequential Cu-Catalyzed Reduction and Pd-Catalyzed Arylation of Silyl Enol Ethers

  摘要：

  {graphic} Enantiomerically enriched beta-substituted diphenylsilyl enol ethers, which can be prepared from Cu-catalyzed asymmetric conjugate reduction, are utilized in the Pd-catalyzed arylation of various aryl bromides. This new method provides a simple route to alpha-arylated cycloalkanones with excellent levels of enantiomeric and diastereomeric purity. The isolation of the intermediate, diphenylsilyl enol ethers is not necessary; the procedure can be carried out in one-pot.
