Dynamic reductive kinetic resolution is applied toward the synthesis of α‐fluorinated‐β‐hydroxy esters using a set of commercially available ketoreductases. In many examples, the reactions are rapid (<1 h) and quantitative with high de and ee. 19F NMR spectroscopy proves useful for analysis of stereochemistry using in‐tube Mosher ester derivatization.
