Ketoreductase (KRED)-catalyzed dynamic reductive kineticresolution (DYRKR) of α-substituted-β-keto arylphosphonates was developed as a generic and stereoselective approach to synthesize chiral α-substituted-β-hydroxy arylphosphonates, with moderate-to-excellent isolated yield (up to 96%), good-to-excellent diastereoselectivity (up to >99 : <1 dr), and excellent enantioselectivity (up to >99% ee) being

The catalyticenantioselective electrophilic fluorination of α-chloro-β-keto phosphonates promoted by chiral palladium complexes has been developed, allowing facile synthesis of the corresponding α-chloro-α-fluoro-β-keto phosphonates with excellent enantioselectivity (up to 95% ee).
