摘要: An expedient method for the synthesis of 5,6-dihydrobenzo[h][1,2,4]triazolo[5,1-b]quinazolines by UV light has been developed. Our aim was to synthesize various α, β-unsaturated carbonyl compounds and further react them with different amines in DMF, presence potassium hydroxide as base, which leads cyclization aromatized products a single step using irradiation at 254 nm. We have performed reaction other bases solvents that lead desired product lower yield. The synthesized ring junction characterized suitable spectroscopic techniques. fluorescence emission spectra were recorded DMF.
