Hypervalent iodine-catalyzed oxylactonization of ketocarboxylic acids to ketolactones.
The hypervalent iodine-catalyzed oxylactonization of ketocarboxylic acids to ketolactones was achieved in the presence of iodobenzene (10 mol%), p-toluenesulfonic acid monohydrate (20 mol%) and meta-chloroperbenzoic acid as a stoichiometric co-oxidant.
