Isomerization of Unprotected Aldoses to 2-Deoxyaldonic Acids Induced by Visible Light/Quinuclidine/Water-Soluble Iridium Complex in Water

Abstract We herein report that a visible light/quinuclidine/water-soluble iridium complex system is highly effective for promoting the isomerization reaction of aldoses to 2-deoxyaldonic acids in water. The product yields and functional group compatibility are much better than those observed with a UV light/water-soluble benzophenone system.
