  Methods for the stereoselective synthesis of 2-fluoroalkenoates. Carbonyl condensation reactions of 3,3-bis(methylthio)-2-fluoropropenal, a highly-functionalized fluoroacrylate cation equivalent

  摘要：

  New methodology for the preparation of 2-fluoroacrylates has been developed on the basis of the reagent 3,3-bis(methylthio)-2-fluoropropenal. This highly-functionalized aldehyde is prepared by the condensation of carbon disulfide with fluoroacetonitrile followed by reduction of the nitrile. It is subjected to nucleophilic addition with organometallic reagents and enolates to yield allylic alcohol products that can be rearranged under acidic conditions to (Z)-2-fluoroacrylate thioesters. Other desired fluoroacrylates are also available via conventional fluorinated Homer-Wadsworth-Emmons or Reformatsky reagents.

  Horner-Emmons fluoroolefination of an aryl aldehyde followed by introduction of a second fluorine via "FBr" addition provides an original approach to the preparation of 1-alkyl-2-aryl-1,2-difluoroethenes. The utility of this procedure is demonstrated by the preparation of (E and Z)-alpha,beta-difluorourocanic acid. Published by Elsevier B.V.
