Abstract: An iron-catalyzed [4 + 2] cyclization for constructing 4-Arylpyrimido[1,2-b] indazoles using 3-Aminopyrazole, phenylacetylene and N, N -Dimethylformamide has been reported, where N, N -Dimethylformamide (DMF) acted one-carbon synthon. The reaction conditions are mild and rapid, with a wide range of applicable substrates.
