AbstractรReaction of 2-unsubstituted 1H-imidazole 3-oxides with isocyanates, isothiocyanates, and dimethyl acetylenedicarboxylate led to the formation of 2-functionalized imidazole derivatives. Stepwise reaction mechanisms via zwitterionic intermediates are proposed. The intermediate [312] cycloaddu
