Catalyst-free Biginelli-type synthesis of new functionalized 4,7-dihydropyrazolo[1,5-: A] pyrimidines

Catalyst-free Biginelli-type synthesis of new functionalized 4,7-dihydropyrazolo[1,5-: A] pyrimidines

The Biginelli-type reaction of 5-amino-3-arylpyrazole-4-carbonitriles with aldehydes and 1,3-dicarbonyl compounds was studied in detail. We found that the reaction requires no catalysts and proceeds in boiling DMF to give 2-aryl-6-RC(O)-4,7-dihydropyrazolo[1,5-a]pyrimidin-3-carbonitriles in good yie...
