An efficient access to novel 2-substituted 1H-imidazole derivatives was developed based on acid-mediated denitrogenative transformation of 5-amino-1,2,3-triazole available through dipolar azide−nitrile cycloaddition (DCR). The proposed approach includes intramolecular cyclization 5-amino-4-aryl-1-(2,2-diethoxyethyl) 1,2,3-triazoles followed by triazole ring opening and insertion in situ formed carbene intermediate into the O-H bond different alcohols under acidic conditions.
