Synthesis of fluorescent [1,2,4]triazolo[1,5-a]pyrimidines and study of their photophysical behavior

The synthesis and photophysics of a family of [1,2,4]triazolo[1,5-a]pyrimidines bearing strategically tuned substituents are reported. Products were obtained in 58–94% yield by reacting 5-amino-1,2,4-triazoles with β-enaminones under solvent-free microwave conditions; notably, precursor heteroamines were obtained in 79...
