Reeves, Jonathan T. published the artcileCopper-catalyzed annulation of 2-formylazoles with aminoiodopyrazoles: Synthesis of new heterocyclic ring systems, Name: 4-Iodo-1-methyl-1H-pyrazol-5-amine, the publication is Journal of Heterocyclic Chemistry (2013), 50(3), 680-683, database is CAplus.
Various 2-formyl azoles underwent CuI/sparteine-catalyzed annulation with 1-substituted 4-iodo-5-aminopyrazoles to produce pyrazolo[3,4-e]pyrrolo[1,2-a]pyrazines and imidazo[1,2-a]pyrazolo[3,4-e]pyrazines. The reaction was demonstrated for 2-formylpyrroles, 2-formylindoles, 2-formylimidazole, and 3-methyl-5-formylpyrazole. 3-Substitution of the iodopyrazole was tolerated.
