Thirty N-substituted Hantzsch 1,4-dihydropyridines were prepared under mild and neutral conditions from N-substituted enaminocarbonyl derivatives and aldehydes activated under the form of N-(1-chloroalkyl)pyridinium chlorides by means of thionyl chloride

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.
