  Synthesis of the Sulfonate Analogue of Seminolipid via Horner−Wadsworth−Emmons Olefination

  摘要：

  The first synthesis of the sulfonate analogue of seminolipid, the main sulfoglycolipid in mammalian sperm, is reported. Installation of the sulfonate unit was accomplished by a quite unexplored strategy based on Horner-Wadsworth-Emmons olefination on a 3'-keto-galactoside, followed by stereoselective double bond reduction.
