A Solvent‐Free Synthesis of Imidazo[1,5‐a]pyridines Using CCl4 as an Oxidant

Journal of Heterocyclic Chemistry, Volume 63, Issue 8, Page 1288-1299, August 2026.
A solvent‐free synthesis of imidazo[1,5‐a]pyridines (Impys) using CCl4 as an oxidant reagent and DBU as the base is informed. An array of Impys derived from different benzylic, heteroaryl aldehydes and others was synthesized in moderate to good yields.
