2-Amino-3-cyano-5-chloromethylpyrazine 1-oxide (I), prepared by the condensation of β-chloropyruvaldoxime with aminomalononitrile tosylate, was deoxygenated with PCl3 to 2-amino-3-cyano-5-chloromethylpyrazine (II). Both I and II were converted by conventional procedures to triphenylphosphonium ylides (Wittig reagents) and, hence, by condensation with aldehydes, to parallel series of 5-alkenylpyrazines (III and IV). Cyclization of IV with guanidine gave 2,4-diamino-6-alkenylpteridines, of interest as intermediates for the synthesis of biopterin and biopterin analogs. Some addnl. reactions of the above pyrazine intermediates are also described.
