1-ARYL- AND 1-BENZYL-3,5-DIETHOXYCARBONYL-1,4-DIHYDROPYRIDINES

Article abstract of DOI:10.1007/BF00552778

The possibility has been studied of using anilines in the Hantzsch synthesis.It has been shown that, with the exception of those containing strong electron-accepting substituents, they take part in this reaction with the formation of 1-aryl-1,4-dihydropyridines.The reaction largely depends on the nature of the substituents in the aniline and in the benzaldehyde and is promoted by electron-accepting substituents in the aldehyde and electron-donating substituents in the amine.The mechanism of the reaction is discussed.A number of 1-benzyl-1,4-dihydroxypyridines have been synthesized.The UV, IR, and PMR spectra and the electro-oxidation of the compounds obtained have been studied.
