New fused
pyrazolo[4,3-e]pyridines were obtained by multi-component reaction of
1,3-dimethyl-1H-pyrazol-5-amine or
3-phenyl-1H-pyrazol-5-amine, aromatic
aldehydes and indan-1,3-dione in the presence of camphor-10-sulfonic acid (CSA)
as an effective catalyst under ultrasound promoted conditions. The antioxidant
activity of the pyrazolopyridine compounds 4b, 5c, 5e, 7a, 7b and 7c were determined.
