Some new 6-amino-1,3-dimethyl-5-(substituted methylidene)aminouracils were synthesized. Most of them were cyclized with triethyl orthoformate as a one-carbon source to afford 1,3-dimethyl-6-substituted pteridine derivatives. Certain uracils gave xanthine

The 1,3-dipolar cycloaddition reaction of pteridine 5-oxides with dimethyl acetylenedicarboxylate resulted in a new ring contraction of the pyrazine moiety to give purines and a 7-deazapurine.
