The addition of a series of stabilized carbon nucleophiles to 3-acyl-1-alkylpyridinium salts. followed by acylation of the intermediate dihydropyridines with trichloroacetic anhydride has been studied. The C-4 adducts resulting from the addition of α-(methylsulfanyl)ester enolates have been converted into synthetically useful 1,2,3,4-tetrahydropyridines.
