1‐(Azidomethyl)benzotriazole and ‐5‐phenyl‐1,2,3,4‐tetrazole as 1, 3‐dipolar cycloaddition components

Abstract

Abstract 1‐(Azidomethyl)benzotriazole reacts with alkynes to give mixtures of isomeric 1,2,3‐triazoles, whereas the interactions of 1‐(azidomethyl)benzotriazole and ‐5‐phenyl‐1,2,3,4‐tetrazole with alkenes proceed regioselectively to form 1,2,3‐triazolines and/or aziridines and enamines in good yields. Diheterocyclosubstituted methanes thus obtained were investigated with respect to thermolysis, α‐lithiation, and reactions with Grignard reagents.
