β‐Cyano‐α‐oxoesters were found to undergo asymmetric aldol addition reaction with acetone in the presence of 10 mol% of L‐proline. With the racemic starting material, dynamickineticresolution (DKR) was achieved in quantitative yields with good diastreroselectivity of up to 85:15 dr and excellent ee up to 99% for the major diastereomer.
