We have successfully synthesized 3,4,5-substituted 1,4-dihydropyridines (1,4-DHPs) from amine hydrochloride salts, aldehydes, and acetals in good yields without the addition of a catalyst. The synthesized 1,4-DHPs exhibit various wavelengths of fluorescen

Methods for the synthesis of the esters of 1,4-dihydropyridine-3,5-dicarbothionic acids by the thionation of the carbonyl analogs with Lawesson's reagent are developed.The influence of the substituents at the nitrogen atom on the course of the thionation reaction is considered.The physicochemical characteristics of this series of substances are analyzed; their reactivity in the reactions of N-alkylation, oxidation, and anion formation is studied.
