Nishiwaki, Nagatoshi published the artcileThree components ring transformation affording substituted 5-nitropyridines and 4-nitroanilines, Recommanded Product: 5-Nitro-2-phenylpyridine, the publication is Letters in Organic Chemistry (2006), 3(8), 629-633, database is CAplus.
The ring transformation of 1-methyl-3,5-dinitro-2-pyridone afforded 2-aryl-5-nitropyridines upon treatment with aromatic ketones in the presence of ammonium acetate. In reactions with aliphatic ketones, 2,6-disubstituted 4-nitroanilines could be prepared in addition to 2,3-disubstituted 5-nitropyridines. In these reactions, dinitropyridone behaved as the synthetic equivalent of unstable nitromalonaldehyde.
