Syntheses and transformations of some 1,2,4‐oxadiazolylpyrazines

Abstract

Abstract Cyanopyrazines with an ortho ‐ammo, 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.
