| Abstract: | The combined application of the three research techniques (ASIS, LIS and the S-O bond anisotropy-induced PMR shift analysis) helped in the assignment of the sulfinyl bond configuration in natural isomeric thionuphlutine (TNF) sulfoxides. As in the NTBN S-oxides the more polar TNF S-oxide, 2, was assigned the beta configuration, and the less polar, 3, the alpha configuration. |
