Abstract

Reaction of 2-nitroacetophenone, furfurol, β-dicarbonyl compounds, and ammonium acetate led to 3-substituted 4-(2-furyl)-5-nitro-6-phenyl-1,4-dihydropyridines, which were oxidized with potassium nitrate in the presence of copper(II) nitrate (10 mol %), leading to the respective 5-nitro-6-phenylpyridines. The performed multicomponent reactions met the general principles of green chemistry. Synthesis of these unsymmetrical 5-nitro-6-phenylpyridines via the formation of 1,4-dihydropyridine intermediates under the conditions of multicomponent reaction significantly shortened the overall reaction time, decreased the number of steps, and improved the yield.
