Photooxidation of Hantzsch 1,4-dihydropyridines (1,4-DHP,1a-1d) by direct irradiation (λ > 300 nm) under an oxygen atmosphere has been carefully examined in this work. Spectroscopic and electrochemical studies demons...
Photooxidation of Hypocrellin A in neutral organic solvents has been studied in detail in our laboratory. The photooxidation product was Hypocrellin A-peroxide which was obtained by the interaction of Hypocrellin A in...

It is very interesting to compare the sensitized photooxidation of indole and its derivatives (tryptophan in especial) acting as the model of the degradation of tryptophan catalyzed by monoxygenase and dioxygenase in ...

Since L. Weil et al. reported the methylene blue-sensitized photooxidation of tryptophan, the sensitized photooxidation of tryptophan by various sensitizers have been studied. However, there are still many problems ab...

In addition to (±)-4-methyl-6-isobutenyl-3,4,5,6-tetrahydro-4H-pyran with many available synthetic sequences, (±)-4-methyl-6-isobutenyl-5, 6-dihydro-2H-pyran (nerol oxide, 1) and (±)-2(1’-methylvinyl)-5-methyl-5-v...
Cyanoaromatic sensitized photoreaction, which proceeds via the sensitizer singlet state, is characterized by chemistry of electron transfer reaction. Foote first observed that those substrates which cannot undergo pho...
Sensitized photooxidation is an important branch of photochemistry both in theory and in practice.In the presence of light and oxygen, the dyes used as sensitizers permit energy transfer to convert molecular oxygen to...
A new effective phototherapeutic drug from Hypocrella bambusae (B. et Br.) Sacc., which is a kind of parasitic fungus growing in Yunnan Province, China, has been successfully used in the treatment of White Lesions of ...
