ABSTRACT Chemoenzymatic dynamic kinetic resolution (DKR) via combined ruthenium and enzyme catalysis was used in the key step of a synthesis of a neonicotinoid pesticide derivative (S)-3. The DKR was carried out under mild conditions with low catalyst loading. The method gives (S)-3 in high enantiomeric excess (98%).
