Solvent-Free Synthesis of Fused Pyrazolo[1,5-a]pyrimidines by Reaction of 5-Amino-1H-pyrazoles and -Triketones
The solvent-free reaction between 5-amino-1H-pyrazoles and -triketones (2-acetyldimedone and 2acetylindandione) leads to the formation of new fused pyrazolo[1,5-a]pyrimidines in good yields. A possible mechanistic route is postulated on the basis of the isolation of the cyclization intermediate. The structures and regiospecificity of the reaction were determined on the basis of nmr measurements...
