Pteridines, XC Syntheses, Oxidations, Properties, and Reactions of 2-Thiopteridine-4,6, 7- trione Derivatives
A new efficient synthesis for 2-thiopteridine-4,6,7-triones (6-10, 15) has been found in the condendation of the appropriate 5,6-diaminopyrimidine (1-5, 14) with oxalic acid in DMF. Analogous condensations with dimethyl oxalate led to S-alkylation probably via an intermediate O-methylation of the DM...
