2005 Enantioselective syntheses O 0031 An Amine Sulfonamide Organocatalyst for Promoting Direct, Highly Enantiose- lective α-Aminoxylation Reactions of Aldehydes and Ketones. — The title catalyst efficiently promotes the highly enantioselective α-addition of nitrosobenzene to ke- tones and aldehydes. The adducts of the latter are directly reduced in situ to yield de- rivatives (V) of enantiopure 1,2-diols. — (WANG*, W.; WANG, J.; LI, H.; LIAO, L.; Tetrahedron Lett. 45 (2004) 39, 7235-7238; Dep.
