| Abstract: | A series of 4-aryl-3-methyl-6-oxo-1-phenyl-4,5,6,7-tetrahydropyrido2,3-c]pyrazoles were synthesized by one-step condensation of arylaldehydes with meldrum acid and 5-amino-3-methyl-1-phenyl- pyrazole under microwave irradiation. The reaction was completed in 2～6 min with good yields. All the products were characterized by IR, 1H NMR spectra and elemental analysis, and 4c was determined by the X-ray diffraction analysis. |
| Keywords: | pyrido[2 3-c]pyrazole microwave irradiation one-step synthesis |
