Tetrahydroxydiboron-mediated metal-free synthesis of 2 H -indazoles via reductive heterocyclization

This is the authors' abstract. We don't add key points for this paper.

A concise, efficient, green and metal-free reductive heterocyclization was established to construct 2 H -indazoles. This method afforded pharmacophoric fragment Compound 4d, and molecular docking suggested it is a potential hERG inhibitor.
