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

A selective method for the synthesis of substituted and annulated pyrano[2,3-d]pyrimidines consisting in acylation of 2-amino-3-cyano-4H-pyrans with acetic anhydride has been developed. It was shown for the first time that acid catalysis is more efficient in this reaction, rather than base catalysis as it has been believed earlier.
