A new method of conformational analysis has been developed, in which energy minimization calculations are combined with lanthanide-induced shift data. First, exhaustive energy calculations are carried out on the free molecules in order to determine the conformations of lowest energy. Then, the coord
A LIS investigation of analogues of amiodarone containing the 3-benzoyl-2-butylbenzofuran system has been performed, utilizing the pseudo-contact shifts of all the proton and carbon nuclei in the molecules. The 13C diamagnetic shifts were removed by use of La(fod), and the pseudo-contact shifts were
The conformation of diphenyl sulphone and 3,4'-dichlorodiphenyl sulphone has been studied by the lanthanideinduced shift (LIS) technique. The lanthanide-sulphone complexation model was established using the conformationally rigid dibenzothiophene sulphone molecule. Several models were tried, includi
