An Electrochemical Route to Novel N‐benzoyl‐1,2,3‐triazoles and Protein Binding Studies of Selected Triazole Derivatives

Abstract

An electrochemical, cost‐efficient and atom‐economic method for the synthesis of novel, structurally unique N‐benzoyl‐1,2,3‐triazole derivatives has been developed via cascade oxidation‐ [3+2] dipolar cycloaddition reaction of readily available propargyl alcohol and benzoyl azide. The electro‐oxidation of propargyl alcohol and subsequent cycloaddition was performed in an undivided cell using graphite rod and stainless‐steel plate as inexpensive electrode materials. Numerous 4,5‐disubstituted‐ N‐ benzoyl‐1,2,3‐triazoles may be synthesized from mili to multi‐gram scale employing this protocol. The biological significance of few selected triazole derivatives were evaluated via protein binding studies.
