Mechanistic details of the Mg2+ ion-activated enantioselective reduction of methyl benzoylformate have been investigated at a B3LYP/6-31G* theory level, using peptide NADH models 1 rigidified with a β-lactam ring. Computation of the reaction pathway revealed important structural differences between the intermediate NADH/Mg2+/ArCOCO2R ternary complexes 3 and the corresponding transition states leading
