Nitrosobenzene reactions
WebbNitrosobenzene or nitrosopyridine are found to be attractive electrophiles in catalytic enantioselective carbon– nitrogen and/or carbon–oxygen bond forming reactions. In the presence of designer Lewis or Brønsted acid catalysts, catalytic enantioselective O- and N-nitroso aldol reaction or nitroso Diels–Alder reaction proceed smoothly.
