Abstract
The synthesis of 1,4-dihydropyridines unsubstituted in the 1-, 2-, and 6-positions from methyl propiolate, aromatic aldehydes, and ammonium acetate in acetic acid is described. The products were oxidised to the corresponding pyridines. Certain features of their n.m.r. spectra are discussed.Keywords
