Azide‐Enolate 1,3‐Dipolar Cycloaddition as an Efficient Approach for the Synthesis of 1,5‐Disubstituted 1,2,3‐Triazoles from Alkyl/Aryl Azides and β‐Ketophosphonates.

A simple procedure to prepare 1,5-disubstituted 1,2,3-triazoles efficiently from alkyl/aryl azides and β-ketophosphonates in the presence of KOH by an azide–enolate 1,3-dipolar cycloaddition in good yields was developed.
