Abstract: Herein, we report an efficient route for coumarin C3‐C4 fused imidazole scaffolds via indium chloride‐mediated single‐step transformation of 4‐azido‐coumarin with amines/aldehydes and coumarin C3‐C4 fused 5‐substituted‐1,4‐benzodiazepine scaffolds with 1,2‐azide‐nitrogen migration through two‐step sequential synthesis via the transitory intermediacy… read more here.
