Popis: (2S,2′S,6R,6′R)-4,4′-(6-Bromopyrido[2,3-d]pyrimidine-2,4-diyl)bis(2,6-dimethylmorpholine) is a novel organic intermediate having pyrido[2,3-d]pyrimidine. It is synthesized by four steps and confirmed by 1H and 13C NMR and FTIR spectroscopy and MS. Meanwhile, the single crystal of the title compound is subjected to the crystallographic analysis and the conformation determination. Moreover, density functional theory (DFT) is used to calculate the optimized structures of the molecule which are compared with the X-ray measurement. The result of the molecular structure optimized by DFT is consistent with the crystal structure determined by single crystal X-ray diffraction. Finally, in order to further investigate some physical properties of the title compound by the B3LYP/6-311G(2d,p) method, the molecular electrostatic potential and frontier molecular orbitals are calculated. The calculated and experimental data show that the title compound has good chemical stability and nucleophilic reactivity. Hirshfeld surface analyses can explain the atom pair contacts of the crystal and the quantitative analysis of intermolecular interactions is performed.
