The copper(II) trifluoromethanesulfonate-catalyzed Pummerer reaction of β-ketosulfoxides with 1,3-dicarbonyl compounds or π-nucleophiles such as phenols, arenes, and tetraallylsilane is reported. The mild conditions provide an efficient entry to a novel class of polysubstituted 3-alkylthiofuran and polysubstituted 3-thiobenzofuran heterocycles from readily available materials.
