Synthesis of (E)- and (Z)-α,β-difluorourocanic acid
摘要:
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.
