  Synthesis of (E,Z)-5-Bromo-1,1-dimethoxy-5-trimethylsilyl-4-pentene, an Upper Chain Allenic Prostaglandin Building Block

  摘要：

  This work explores the synthetic route to allenic prostaglandins. In a search for more efficient and reliable methods for the introduction of the allene moiety into the side chains of prostaglandins, the synthons, the (E) and (Z) isomers of 1-bromo-5,5-dimethoxy-1-trimethylsilyl-1-pentene (13a) and (13b), have been prepared and converted to R,S-1,1-dimetboxy-6-phenyl-4,5-hexadiene (16), a prostaglandin analog.
