Cyclocondensation of sodium nitromalone dialdehyde with different enamines gave 3-acetyl(benzoyl, cyano, cyclopropanoyl, carbethoxy)-2-methyl(phenyl)-5-nitropyridines. With the aim of increasing the yield of pyridines we have activated the nitromalonic dialdehyde through acylation of its enol form.
