palladium‐catalyzed asymmetric OHinsertionreaction was developed. Palladium complexes with chiral spiro bisoxazoline ligands promoted the insertion of α‐aryl‐α‐diazoacetates into the OH bond of phenols with high yield and excellent enantioselectivity under mild reaction conditions. This palladium‐catalyzed asymmetric OHinsertionreaction provided an efficient and highly enantioselective method for the preparation
