Copper-Catalyzed C–C-Coupling/Aza-Henry Domino Reaction of Nitriles to Synthesize 4-Nitro-2H-chromen-3-amines
摘要
Abstract
2-(2-Haloaryloxy)acetonitriles reacted with nitromethane in the presence of DBU and copper(I) iodide to afford 4-nitro-2H-chromen-3-amines as a result of consecutive arylation and aza-Henry reactions.
