Mono- and diquaternary pyridinium salts substituted in 3-position with electron withdrawing groups, react with alcohols under basic conditions to give 6-alcoxy-1,6-dihydropyridines.Symmetric dipyridinium salts react in aqueous alkaline solution to products with 6-pyridone and dihydropyridine moiety.This redox reaction depends on the length of the bridge connecting the pyridinium rings.Pyridinium salts can be reduced by aluminiumtriisopropoxide to 1,4-dihydropyridines. - Key words: Pyridinium Salts, Insertion Reaction, Redox Reaction
