Abstract

We report herein our initial results of the catalytic enantioselective alpha-oxytosylation of propiophenone using chiral hypervalent iodine reagents. Low to moderate enantioselectivities of the alpha-oxytosylate are seen using a variety of ortho substituted chiral aryl iodides as catalysts. We also report our efforts using a variety of co-oxidants and reaction conditions in order to optimize this reaction. To our knowledge, this represents the first example of enantioselective organocatalysis using hypervalent iodine reagents.
