摘要：

Intermolecular cycloadditions between trialkyl 1,2,4-triazine-4,5,6-tricarboxylates and protected 2-aminoimidazole gave 1H-imidazo[4,5-c]pyridines (3-deazapurines) and the rearranged 3H-pyrido[3,2-d]pyrimid-4-ones (8-deazapteridines). No cycloadditions were observed with imidazole and 2-phenylimidazole. (C) 1997 Elsevier Science Ltd.
