Functionalization of carboxylic anhydrides at α-carbon with hypervalent iodine reagents: one-pot conversion of anhydrides to 2-sulfonyloxycarboxylate esters

The treatment of carboxylic anhydrides with iodine(III) sulfonate reagents at ca. 100°C and esterification of the reaction mixtures with MeOH/TsOH•H 2 O affords 2-sulfonyloxycarboxylate esters. This is consistent with enolic behavior in the anhydrides.
