Abstract A metal‐free, iodine‐mediated protocol has been developed to synthesize indazoloquinoxaline derivatives from readily accessible substrates such as 2‐(2 H ‐indazol‐2‐yl)anilines and aryl methyl ketones. This operationally simple, one‐pot reaction proceeds through iodine/DMSO‐mediated C(sp 3 )‐H oxidation of ketones, followed by imine formation annulation furnish the desired products. wide range including drug‐derived substrates, were compatible in present reaction. Further, is scalable, demonstrating its applicability on a larger scale.
