Azole‐Substituted Triazole Formation through Organocatalytic Cycloaddition of β‐keto Azoles and Aryl Azides

A highly efficient metal free regioselective approach for the synthesis of a novel azole substituted triazoles via organocatalytic [3+2] cycloaddition between β‐keto azoles and aryl azides at room temperature is reported. The proposed methodology is well tolerated with range of substituents in the β‐keto azoles and aryl azides with good to excellent yield (81–94 %) without column chromatography as purification technique under ambient reaction conditions.
