  An improved synthesis of naphthoate precursors to olivin

  摘要：

  An improved synthesis of olivin synthetic intermediate 3 is described. The synthesis involves the Homer-Wadsworth-Emmons coupling of 14 and 16, the diastereoselective vinylcuprate addition to enone 20, and the condensation of isocoumarin 25 and methyl acetate. A parallel sequence starting from allyl ether 26 has provided naphthoate 35 that is suitably differentiated for glycosylation studies.
