for the synthesis of 1‐substituted 1H‐tetrazole derived from α‐amino acid ethyl esters was demonstrated in the presence of zinc oxide nanoparticles (ZnO NPs) under conventional conditions, with heating (at 60 and 80°C and under reflux) compared with ultrasonic. The effect of solvent was investigated to reveal that the solvent system CH3CN/H2O was optimum to obtain 1‐substituted 1H‐tetrazole in high yield
