Synthesis, characterization, and in vitro biological studies of some novel pyran fused pyrimidone derivatives

A variety of pyrano[2,3-d]pyrimidine-5-one derivatives 5,6(a-j) have been synthesized from 6-amino-4-(substituted phenyl)-5-cyano-3-methyl-1-phenyl-1,4- dihydropyrano[2,3-c]pyrazole derivatives 4(a-j) via cyclization using formic acid and acetic acid. All
