Photochemistry of 1,3-dimethyluracil. A novel photochemical reaction leading to 3,5-dialkoxycarbonyl-1,2-and -1,4-dihydropyridines
Abstract
A new photochemical reaction of 1,3-dimethyluracil is reported. Irradiation of 1,3-dimethyluracil in methanol leads to a fluorescent mixture of 1,4-dihydro- and 1,2-dihydro-3,5-dimethoxycarbonyl-1-methylpyridines. Results from photolysis in other alcoholic solvents are also reported.
