Abstract Starting from a chiral substituted benzaldehyde diastereomeric arylmethylidenepyrrolinones were accessible. The geometrical structures of the corresponding isomers were investigated by lanthanide ion induced shift technique and UV spectroscopy. By equilibration studies, D-NMR measurements and kinetic data a complete picture of the various ground state enthalpy differences as well as the activation energies of the transition paths was gained. The results are in accord with the barriers determined for two simple model derivatives belonging to the class of atropisomeric sterically hindered styrenes.
