Description
  • The development of a suitable methodology for configuration determination of chiral biologically active compounds containing sulfur, nitrogen, or phosphorus atom as a chiral center (sulfoxides, N-oxides, phosphine oxides, phosphinates and phosphonates). The combination of NMR experiments in solution and in solid state with quantum chemical calculations (geometry optimization, calculation of NMR chemical shifts and spin-spin coupling constants) will be used. We would like to explore the effects of magnetic anisotropy of S-O, N-O and P=O functional groups on chemical shifts and coupling constants of the other atoms in the molecule. In the frame of the project we would like to investigate geminal coupling constants J(P-C-C) and J(P-C-H) and their dependence on the structure and configuration of modified nucleotide phosphonates containing an asymmetric carbon in the neighboring position to the phosphorus atom.  (en)
