  A Convenient Synthesis of 3-(Aryl)substituted 2,4(1H,3H)-Pteridinediones and Their Absorption and Fluorescence Spectorscopic Characteristics

  摘要：

  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 remarkable difference in the reactivity is observed among heterocumulenes. The absorption and fluorescence spectroscopic characteristics of the titled compounds are also discussed.
