Abstract A simple route for the synthesis of Boc-protected tetrazoleanalogs of amino acids starting from N α-Boc amino acids has been described. The [2 + 3] cycloaddition of Boc-α-amino nitrile and sodium azide in the presence of a catalytic amount of zinc bromide yielded the desired tetrazoles in good yields and purity. All the compounds obtained have been characterized by 1H and 13C-NMR and mass
