摘要：
A novel transformation of alpha-hydroxy acids to alpha-trifluoromethylated and alpha-perfluoroalkylated acyloins was efficiently realized by utilizing trifluoroacetic or perfluoroalkylcarboxylic anhydrides in the presence of pyridine, in which probable intermediates were meso-ionic 1,3-dioxolium-4-olates.
