An (Au)some coupling! Gold‐catalyzed cascade CO cyclizations of benzyl‐substituted allenoate esters followed by intramolecular oxidative CC cross‐coupling involving aryl CH functionalization were performed with Selectfluor as the oxidant (see scheme). This operationally simple and mild procedure benefits from complete axis‐to‐center chirality transfer and allows for the preparation of surprisingly
