摘要：
Photosensitized oxidation of unsymmetrically substituted 1,4-dihydropyridines using dye sensitizers methylene blue, rose bengal and tetraphenylporphyrin by taking visible light source resulted in the aromatization of dihydropyridine ring and formation of the corresponding pyridine derivatives. Comparison of the results obtained under photosensitized reaction with those obtained by direct photo-oxidation indicated a very fast and smooth reaction of these compounds and formation of pyridine derivatives using theses dyestuffs.
