Heteroaromatization with 4-Hydroxycoumarin Part II: Synthesis of some new pyrano[2,3-d]pyrimidines, [1,2,4]triazolo[1,5-c]pyrimidines and pyrimido[1,6-b]-[1,2,4]triazine derivatives

A variety of novel [1,2,4]triazolo[1,5-c]pyrimidine-13-ones (4a-f) and (5b-d) could be obtained via reaction of 9-amino-7-(4'-chlorophenyl)-8,9- dihydro-8-imino-6H,7H-[1]benzopyrano[3′,4′:5,6]pyrano[2,3-d] pyrimidine-6-one (3) with a variety of reagents. Pyrano[2,3-d]pyrimidine-6-ones 5a, 8a-c and pyrimido[1,6-b][1,2,4]-triazine-3,14-dione (6) were also prepared. The antimicrobial activity of some of the synthesized compounds was tested.
