4-oxo-2,2,6,6-tetramethylpiperidinyl-1-oxy radical (TEMPO), a nitroxide, oxidized 4-substituted Hantzsch 1,4-dihydropyridines (DHP) under UV irradiation in CH₃CN to give aromatic products in good yields. A possible mechanism for the oxidation was suggested.
- Nitroxide,
- Hantzsch dihydropyridines,
- photoinduced electron transfer
