An asymmetric synthesis of elusive chiral cyclopentadienes has been developed by gold(I)‐catalyzed alkoxycyclization of 1,3‐dien‐5‐ynes. The application of these substrates in completely diastereoselective Diels–Alder cycloaddition reactions, which can be carried out in onepotfrom achiral 1,3‐dien‐5‐ynes, allows the preparation of highly functionalized products bearing five stereogenic centers with
