## Abstract A novel proline derivative, (4__R__)‐4‐(β‐Naphthalenyl)methoxy‐(__S__)‐proline, was conveniently prepared from the naturally occurring (4__S__)‐hydroxy‐(__S__)‐proline; 5 mol % of this compound efficiently catalyzes the asymmetric aldol reactions of various benzaldehydes with acetone in
