Article abstract of DOI:10.3987/COM-92-S(T)89

3-(Aryl)substituted 2,4(1H,3H)-pteridinediones are synthesized in high yields by addition and simultaneous cyclization of methyl 3-amino-2-pyrazinecarboxylate with isocyanates.The remarcable difference in the reactivity is observed among heterocumulenes.The absorption and fluorescence spectroscopic characteristics of the titled compounds are also discussed.
