Solvent-free regioselective synthesis of 6- and 7-substituted pteridines under microwave irradiation

Article abstract of DOI:10.1134/S1070428006010210

Reactions of 5,6-diaminouracils with α-keto aldehydes over acidic and neutral aluminum oxide under microwave irradiation gave the corresponding 6- and 7-substituted 1,2,3,4-tetrahydropteridine-2,4-diones in 63-79% yield with high regioselectivity. Pleiade
