An enantioselective preparation of (S)-metolachlor has been accomplished. The syntheticroute featured the asymmetric preparation of chiral intermediates and the final (S)-metolachlor from commercially available (R)-propylene oxide and a key Fukuyama’s process. The key steps, control points, separation purifications, and the whole process are optimized, and the target compound has been successfully
