The highly efficient synthesis of 3‐ethylideneflavanones through sequential rhodium(I)‐catalyzed hydroacylation of terminal aryl‐substituted 1,3‐enynes with chelating aldehydes and annulation is described. This straightforward protocol highlights an unprecedented C3‐regioselective hydroacylation of 1,3‐enynes, excellent functional group compatibility, and complete atom economy.
