enantioselective Heck–Matsudadesymmetrization reaction was accomplished by using 3‐cyclopentenol to produce chiral five‐membered 4‐aryl cyclopentenol scaffolds in good yields and high ee’s, together with some 3‐aryl‐cyclopentanones as minor products. Mechanistically, the hydroxyl group of 3‐cyclopentenol acts as a directing group and is responsible for the cis‐ arrangement in the formation of the 4‐aryl‐cyclopentenols
