Nafion-H catalyzed isomerization of glycidic to α-hydroxy-β,γ-unsaturated esters: application in the synthesis of a trifluoromethylated vinylic epoxide

Facile Nafion-H catalyzed isomerization of glycidic esters to α-hydroxy-β,γ-unsaturated esters is reported. These compounds are useful synthetic intermediates. Application in the synthesis of a trifluoromethylated vinylic epoxide is demonstrated
