The syntheses of alpha- and beta-trifluoromethyl epoxysulfones 1 and 2 are described. Compound 1 reacts with nucleophiles and bis-nucleophiles to furnish trifluoromethyl ketones and triRuoromethyl heterocycles in good yield, while its isomer 2 leads to the opposite thiazole regioisomers with thioamides.
