Le, Song Thi published the artcileSynthesis of 2-Aryl-5-Nitropyridines by Three-Component Ring Transformation of 3,5-Dinitro-2-Pyridone, SDS of cas: 89076-64-2, the publication is Asian Journal of Organic Chemistry (2014), 3(3), 297-302, database is CAplus.
2-Arylated-5-nitropyridines were efficiently synthesized by a three-component ring transformation of 3,5-dinitro-2-pyridone with aromatic ketones in the presence of ammonium acetate wherein the dinitropyridone served as a synthetic equivalent of an unstable nitromalonaldehyde. 2,8-Diazabicyclo[3.3.1]non-3-ene derivative was formed as a byproduct and was converted into nitropyridines by heating in the presence of ammonium acetate. This exptl. fact implied that the former compound was a kinetically controlled product and the latter was a thermodynamically controlled product because of the aromatization. This eco-friendly method was applicable to various kinds of aryl and (hetero)aryl ketones to afford the corresponding (hetero)arylated pyridines in good to excellent yields.
