Using a facile and cost-effective method, nine bicyclic 1,2,3-triazine 2-oxides were synthesized from o-aminocyanide substrates through an unusual nitration cyclization. The reaction mechanism was studied experimentally and theoretically. Moreover, nine 1

Syntheses of 4-aminopteridine 3-oxides are described.The pyrimidine part undergoes transformations with various reagents to give 4-hydroxyaminopteridines, substituted pyrazines, or substituted 1,2,4-oxadiazolylpyrazines. s-Triazolo(1,5-a)pyrazines can be prepared from 1,2,4-oxadiazolylpyrazines.The ring opening of the pyrimidine part of pteridines proceeds either py a C2-N3 or N3-C4 bond cleavage.

Cyanopyrazines with an ortho-amino, oxo and other groups are transformed into the corresponding amidoximes.From these the corresponding 1,2,4-oxadiazolyl derivatives can be prepared and interconversions to the corresponding pteridine 3-oxides are described.
SOME NEW SYNTHETIC APPROACHES FOR THE PREPARATION OF PTERIDINE-3-OXIDES AND PTERIDINES

Starting from 2-amino-3-cyanopyrazine some new syntheses of 4-substituted pteridines and pteridine-3-oxides have been devised.
