Oxazoline and bisoxazoline derivatives are known as ligands for potential catalysts of asymmetric syntheses [1, 2]. Replacement of oxygen atom by nitrogen would cause an increase in basic properties and nucleophilicity of such heterocyclic ring, ie. imidazoline and, still more, imidazole. Recently, such derivatives have increasingly been attracting interest, which is documented not only by research activities in the field of synthesis, but ...
