eng	Highly enantioselective nitroaldol reaction catalyzed by copper(ii) complexes derived from substituted 2-(pyridin-2-yl)imidazolidin-4-one ligands	Ten optically pure substituted 2-(pyridin-2-yl)imidazolidin-4-ones were prepared and characterized. The Cu(II) complexes of the respective ligands were studied as enantioselective catalysts of the nitroaldol (Henry) reaction of aldehydes with nitromethane, giving the corresponding substituted 2-nitroalkanols. In the case of an anti arrangement of the imidazolidin-4-one ring, the obtained result was 91–96% ee, whereas in the case of syn arrangement, a significant drop to 25–27%ee was observed.	enantioselectivity; nitroaldol reaction; catalysis; copper(II) complexes; 2-pyridin-2-ylimidazolidin-4-one;
