| Abstract: | Novel pyrazolopyrimidines derivatives were synthesized regioselectivly in one‐pot three‐component approach by Fe+3‐montmorillonite catalyzed condensation of 3‐amino‐5‐methyl pyrazole, arylaldehydes, and dimethylmalonate in THF under ultrasonic irradiations and conventional conditions. This rapid method produced the products in short reaction times and good yields. |
