in contrast to the formation of 1,4- dihydro compounds from reduction of nicotinamide adenine dinucleotide(NAD©€) in biological systems, chemical reduction of pyridinium salts gives different reduction products depending on the reducing agents and substrates.However, the mechanism of the reductions has not been fully understood. Therefore, it would be of interest to study the reduction of N-arylpyridinium salts,in which aryl groups with various substituents differing in electronic effect can be easily incorporated,and to compare their reduction  products.  It  is  also  known  that  some  of 1,2-dihydroquinolines  isomerize  to  the  corresponding 1,4-isomers. The  study  on  the  isomerization  of  N-aryldihydropyridines is expected to give valuable informations on the factors underlying the process.
