Among numerous approaches for the synthesis of condensed heterocycles bearing a pyrazole nucleus, the intramolecular cyclization of a suitable ortho-substituted nitroaromatic and nitroheteroaromatic precursors is one of the most convenient routes. This review summarizes recent developments in the application of this approach for the synthesis of fused pyrazoles, their 1-oxides, and 1-hydroxy derivatives.
