摘　　要：The oxidation on 1,4-substituted Hantzsch 1,4-dihydropyridines with nitrosonium tetrafluoroborate (NO+BF4-) in acetonitrile gave Hantzsch pyridines in good yields. In some cases the dealkylation occurred. The evidences to draw the mechanism were presented.The oxidation on 1,4-substituted Hantzsch 1,4-dihydropyridines with nitrosonium tetrafluoroborate (NO+BF4-) in acetonitrile gave Hantzsch pyridines in good yields.
