  The stereoselective syntheses of a library of novel spiro-tethered pyrazolo[3,4-b]quinoline–pyrrolidine/pyrrolothiazole/indolizine–oxindole/acenaphthene hybrid heterocycles have been achieved through the 1,3-dipolar cycloaddition of azomethine ylides generated in situ from α-amino acids and 1,2-diketones to dipolarophiles derived from pyrazolo[3,4-b]quinoline derivatives.

  4‐b]pyridines through a rhodium‐catalysed intermolecular cyclization of pyrazol‐5‐amine and cyclic 1,3‐diketone‐2‐diazo compounds, has been developed. A methyl carbon of N,N‐dimethylformamide (DMF) performed as a carbon‐hydrogen source for the construction of the pyridine ring. Various pyrazolo[3,4‐b]pyridine derivatives were obtained under mild conditions using air as the terminal oxidant.

  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 β-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
