Abstract

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 ...
