Abstract

Previously unknown 1,4-dihydropyridines containing acetyl, amide, benzoyl, ester, and cyano groups together with a nitro group were synthesized with preparative yields by a two-component Hantzsch synthesis based on 2-nitro-1,3-diphenylpropenone and various enamines. The nitrodihydropyridines were aromatized with sodium nitrite in acetic acid. The quaternary salts of low-basicity pyridines were produced with dimethyl sulfate and methyl fluorosulfonate.
