correlates with the activation barriers for C-N bond rotation may have implications for other useful synthetic organic reactions involving similar substrates. Finally, these studies were extrapolated to understanding the poor reactivity of N-acyl oxazolidinones, as those derived from Evans chiral auxiliaries, with N-tert-butyl acrylamide. These couplings appear to be dominated by the activation energy for addition
