Abstract
On interaction of alicyclic 1,5-diketones and the products of their intramolecular aldol condensation with 2- and 4-nitroanilines and 2,4-dinitroaniline reduction occurs of the nitro group by the intermediately formed 1,4-dihydropyridine derivatives. The reaction products are N-nitrophenyl- and N-aminophenylpyridinium salts and also N,N-phenylenebispyridinium salts.
