Synthesis, Physico-Chemical, Hirschfield Surface and DFT/B3LYP Calculation of Two New Hexahydropyrimidine Heterocyclic Compounds

Abstract

Two new hexahydropyrimidine compounds were prepared in high yield by condensation of an equimolar amount of 1,3-diamine with 2-dipyridylketone at room temperature in dichloromethane. The desired hexahydropyrimidine structures were confirmed on the basis of their UV-Visible, elemental analysis, FT-IR, 1H-NMR, TG/DTG, and EI-MS data. Hirschfield and DFT/B3LYP theoretical analyses were performed and their output results were compared to experimental data.
