Electrochemical Three‐Component Reaction to Construct N ‐( α ‐alkoxyalkyl)benzotriazoles

N ‐( α ‐alkoxyalkyl)benzotriazoles are of great importance for biochemical and antitumor activity. A feasible protocol has been developed for the synthesis of N ‐( α ‐alkoxyalkyl)benzotriazoles using azoles, aldehydes and alcohols as substrates under electrochemical conditions. The reaction is carried out under acid catalyst‐ and oxidant‐free conditions, so that a variety of synthetically useful nitrogen heterocyclic derivatives can be obtained. More meaningfully, a gram‐scale synthetic approach was employed to demonstrate the scale‐up applicability of this transformation.
