ROLE OF STERIC FACTORS IN INTRAMOLECULAR H-BOND FORMATION AND PECULIARITIES OF ELECTROCHEMICAL OXIDATION OF ETHYL 6-ALKYLSULFANYL-5-CYANO-2-METHYL-4-PHENYL-1,4-DIHYDROPYRIDINE-3-CARBOXYLATES

Аннотация

6-Alkylsulfanyl-5-cyano-2-methyl-4-phenyl-1,4-dihydropyridine-3-carboxylates containing electron-donating or electron-withdrawing groups were prepared by alkylation of 6-thioxo-1,4,5,6-tetrahydropyridine-3-carboxylate with alkyl halides. The H-bond formation in the case of 6-alkylsulfanyl substituent bearing sterically small hydrogen bond acceptor explains a partial lack of correlation of the electrochemical oxidation potentials with Taft's σ*-constants.
