Abstrakt:	Hydrogenation of the diastereouniform 3-[1-aryl(hetaryl)-2-nitroethyl]-3-methoxycarb-onyl-4-phenyl(3-pyridyl)-2-pyrrolidones is accompanied by intramolecular acylation of the formed amino group to afford the diastereomerically pure 4,4′-aryl(hetaryl)-3,3′-spirobi-[2-pyrrolidones]. The structures of these diastereomers were characterized by IR, H and C NMR spectroscopy using heteronuclear correlation experiments, and X-ray diffraction study. [ABSTRACT FROM AUTHOR]
