Hypervalent iodine-catalyzed oxylactonization of ketocarboxylic acids to ketolactones
摘要:
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. (C) 2009 Elsevier Ltd. All rights reserved.
