An enantioselective primary amine-catalyzed total N-selective nitroso aldol reaction (N-NA) was achieved through the oxidation of primary aromatic amines to the corresponding nitrosoarenes catalyzed by selenium reagents and 30% H2O2. This protocol provides a facile and highly efficient access to α-hydroxyamino carbonyls bearing chiral quaternary centers under exceedingly mild and green reaction conditions with high chemo-and enantiocontrol.

A rhodium-catalyzed annulative reaction between azobenzenes and nitrosoarenes has been developed, leading to a series of phenazines in moderate to good yields. This procedure proceeds with sequential chelation-assisted addition of aryl C-H to nitrosoarenes and ring closure by electrophilic attack of azo group to aryl. During this transformation, the azo group served as not only a traceless directing group but also a building block in the final products.
Synthesis of 1-substituted benzo[c]isoxazol-3(1H)-imines via tandem nitroso-ene/intramolecular cyclizations of 2-nitrosobenzonitrile

(Chemical Equation Presented) Instead of reacting via the expected coarctate cyclization pathway, 2-nitrosobenzonitrile undergoes a tandem nitrosoene/intramolecular cyclization to form benzo[c]isoxazol-3(1H)-imines in very good yields under neutral conditions and at moderate temperatures. Treatment of three of the imines with HBF4 results in dimerization/condensation to furnish unusual, delocalized cationic systems.
