  描述：

  2,2-dichloro-3-hydroxy-4-phenyl-pentanoic acid isopropyl ester 在 samarium diiodide 作用下， 以 四氢呋喃 为溶剂， 反应 1.0h， 以85%的产率得到2-chloro-4-phenyl-pent-2-enoic acid isopropyl ester

  名称：

  Synthesis of ( Z )-α-chloro-α,β-unsaturated esters with complete stereoselectivity promoted by samarium diiodide

  摘要：

  Stereoselective beta-elimination in alpha,alpha-dichloro-beta-hydroxyesters 2 was achieved by using samarium diiodide, yielding (Z)-alpha-chloro-alpha, beta-unsaturated esters 1. The starting compounds 2 were easily prepared by reaction of the lithium enolate of ethyl dichloroacetate with different aldehydes at -78 degreesC. A mechanism to explain this process is proposed.
