This study highlights the great importance of even small perturbations in molecular geometry for the definition of chiroptical properties, and therefore for the stereochemical characterization, of chiral drugs. A thorough DFT conformational analysis and TD-DFT calculations were needed for a reliable assessment of the absolute configuration of a (3R)-3-hydroxy-4-thienyl-β-lactam derivative, for which semi-empirical β-lactam sector rules failed to predict the correct stereochemistry.

Abstract
This study highlights the great importance of even small perturbations in molecular geometry for the definition of chiroptical properties, and therefore for the stereochemical characterization, of chiral drugs. A thorough DFT conformational analysis and TD-DFT calculations were needed for a reliable assessment of the absolute configuration of a (3R)-3-hydroxy-4-thienyl-β-lactam derivative, for which semi-empirical β-lactam sector rules failed to predict the correct stereochemistry.
