2,4-Diamino-6-substituted pteridines (I) are prepared Reaction of an α-keto-aldoxime with aminomalononitrile gives 2-amino-3-cyano-5-substituted pyrazine 1-oxides which yield 2,4-diamino-6-substituted pteridine 8-oxides upon cyclization with guanidine. 2,4-Diaminopteridines are then obtained by deoxygenation of the corresponding 8-oxides, or alternately by prior deoxygenation of these pyrazine 1-oxides, followed by cyclization with guanidine. The conversion of 2-amino-3-cyano-5-methylpyrazine 1-oxide to the corresponding 1,4-dioxide, and a number of chem. transformations of this latter intermediate, are also described.
