Rapid and efficient oxidation of Hantzsch
1,4-dihydropyridine with Potassium peroxomonosulfate is reported. The
Mn(III)-salophen/monopersulfate catalytic system converts
1,4-dihydropyridines to their corresponding pyridine derivatives at room
temperature in a 1:1, CH3CN/H2O mixture. The
ability of various Schiff base complexes in the oxidation of
1,4-dihydropyridine was also investigated.
