Rhodium(II) Acetate-Catalysed Cyclization of Pyrazol-5-amine and 1,3-Diketone-2-diazo Compounds Using N,N-Dimethylformamide as a Carbon-Hydrogen Source: Access to Pyrazolo[3,4-b]pyridines

Access to pyrazolo[3,4-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. (Figure presented.).
