Pyrimidines. XXXIII [1]. Synthesis and properties of new fervenulin derivatives

A series of new 3-substituted fervenulin (6,8-dimethylpyrimido[5,4-e]-1,2,4-triazine-5,7-dione) (1) derivatives have been synthesized by modifying the 3-alkyl- and aralkyl side-chains. Brominations of 3-methyl-15, 3-ethyl-16- and 3-benzylfervenulin (17) l

A NEW SYNTHESIS OF FERVENULINS AND ALLOXAZINES. THERMOLYSIS AND PHOTOLYSIS OF 6-AZIDO-1,3-DIMETHYLURACIL WITH TETRAZOLES AND BENZOTRIAZOLES

Thermolysis of 6-azido-1,3-dimethyluracil(1) in the presence of 5-substituted tetrazoles(2) gave 3-substituted fervenulins(4), which were also synthesized from the intermediates(3) prepared by photolysis of (1) with (2).Irradiation of (1) with benzotriazoles(6) in tetrahydrofuran gave 6-(benzotriazol-1-yl)uracils(7), which were irradiated in methanol to afford alloxazines (8).
