A New Protocol for Catalyst-Free Regioselective Synthesis of 5,9-Dihydropyrimido[5,4- e ][1,2,4]triazolo[1,5- a ]pyrimidine-6,8(4 H,7 H)-diones

Article abstract of DOI:10.1055/s-0034-1379953

A novel, environmentally friendly synthesis of 5,9-dihydro-pyrimido[5,4-e][1,2,4]triazolo[1,5-a]pyrimidine-6,8(4H,7H)-diones has been developed by using a one-pot condensation of 1,3-dimethylbarbituric acid, 3-amino-1H-1,2,4-triazoles, and aromatic aldehydes. The reactions were established based on green chemistry principles under catalyst- and solvent-free conditions.
