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. (Figure presented.).
