Benign decay vs. photolysis in the photophysics and photochemistry of 5-bromouracil. A computational study.
The excited state potential energy surface of 5-bromouracil has been studied with ab initio CASPT2//CASSCF calculations to rationalize the competition between the benign decay and the photolysis found experimentally. The surface is characterized by an extended region of degeneracy between S(1) and S(0). The access to this region has been studied with minimum energy path calculations from the FC...
متن کاملPhotochemistry of 5-allyloxy-tetrazoles: steady-state and laser flash photolysis study.
The photochemistry of three 5-allyloxy-tetrazoles, in methanol, acetonitrile and cyclohexane was studied by product analysis and laser flash photolysis. The exclusive primary photochemical process identified was molecular nitrogen elimination, with formation of 1,3-oxazines. These compounds were isolated in reasonable yields by column chromatography on silica gel and were fully characterized. D...

متن کاملSynthesis and docking analysis of new heterocyclic system of tetrazolo[5',1':2,3][1,3,4]thiadiazepino [7,6-b]quinolines as aldose reductase inhibitors
Objective(s):In recent years, the chemistry of Tetrazolo[5',1':2,3][1,3,4]thiadiazepino [7,6-b]quinolines have received considerable attention owing to their synthetic and effective biological importance which exhibits a wide variety of biological activity. As the inhibitor of aldose reductase, the aforementioned compounds may have implication in preventing complications of diabetes. Materials...
متن کاملSynthesis and quantitative structure–activity relationship study of substituted imidazophosphor ester based tetrazolo[1,5-b]pyridazines as antinociceptive/anti-inflammatory agents
A high-yielding general synthesis of imidazophosphor ester based tetrazolo[1,5-b]pyridazines is described. A conjugated reaction between 3,6-diazidopyridazine and different types of phosphonyl carbanion reagents followed by intramolecular cyclization afforded the target products, by using sodium ethanolate solution as a reaction medium. Among the products, five compounds, at a dose of 50 mg per...
