Asymmetric reactions of nitroso compounds offer unique advantages for the formation of CÀO and CÀN bonds especially in the area of biomedically relevant heterocycles.[1] Heretofore, however, diastereo-and enantioselective transformations of nitroso compounds have been limited to stoichiometric chiral auxiliary-controlled processes.[2] Several recent examples of catalytic enantioselective transformations of nitrosoarenes have ...
