  Stereoselective Synthesis of Z-α-Aryl-α,β-unsaturated Esters

  摘要：

  An efficient method for the stereoselective synthesis of (Z)-alpha- arylacrylates is described. Treatment of alpha-hydroxyesters with triflic anhydride and pyridine at 0 C followed by warming to room temperature afforded the corresponding (Z)-alpha-aryl-alpha,beta-unsaturated esters in very good yields and excellent stereoselectivity.
