International audience; An efficient access to 4-aryl imidazole scaffolds is described in two steps and one operation. Cyanoaryl-imidazolines are easily obtained by a (3 + 2) heterocyloaddition involving cyanobenzenes as dipolarophiles and a non-stab

Non-stabilized azomethine ylide 4a reacts smoothly at room temperature with a variety of uncomplexed aromatic heterocycles and carbocycles on the condition that the ring contains at least one or two electron-withdrawing substituents, respectively. Ar
