摘要

Pyrazolo[ 3,4-b] pyridine derivatives have been synthesized via one-pot condensation of 3-methyl-1-phenyl-1H-pyrazolo-5-amine (1), formaldehyde (as paraformaldehyde) (2) and beta-diketones (3) under microwave irradiation in aqueous media catalyzed by InCl3. This process has been found to be useful in the preparation of new N-fused heterocycle products in good to excellent yields. Further treatment of pyrazolopyridines (4a and 4e) with aldehyde aromatics (5a-l) afforded chalcone analogs.
