Abstract
The thermodynamic stability of the axial (а) and equatorial (е) forms of the S- and R-enantiomers of 5,5,6-trihydroxy-6-methyldihydropyrimidine-2,4(1Н,3Н)-dione was studied by quantum-chemical methods. The equilibrium geometrical parameters and thermodynamic characteristics were determined by the DFT method using the TPSS functional combined with the 6-311+G(d,p) split-valence basis set including the d and p type polarization functions. The Chemcraft and VMD programs were used to visualize the geometrical structure. The most stable forms of 5,5,6-trihydroxy-6-methyldihydropyrimidine-2,4(1Н,3Н)-dione are Se and Re in both the gas phase and aqueous and organic (DMSO) media. The activation barrier of the rearrangement inside the ring is 21.22–24.93 kJ/mol depending on the medium.
