Abstrakt: Some quaternary salts of asymmetric substituted pyridines with functional group at the 3- and 5-positions have been synthesized. It has been established that when there is an ester group present, the latter participates in the recyclization of the salts on treatment with alkali, resulting in the formation of pyridine-2-ones.
