    • The structure of imidazolidine products was examined by molecular mechanic simulation with the crystal structure coordinates of the 2-deoxyribose moiety of thymidine and N1-carbamoyl-2-oxo-4,5-dihydroxyimidazolidine (ref 32, Using a torsional space grid search, the O4′-C1′-N1-C2 torsional angle (χ) of imidazolidine nucleosides was sterically restricted to the syn (40-60°) and anti (160-240°) conformations. The other possible conformations were not allowed because of bad contacts between the 2-deoxyribose and imidazolidine units including the following atoms: C2O2-H2′C2′ (60-180°, O5-H2′ (240-300°, and C2O2-O4′ 300-60°
