Right direction: The presented enantioselective strategy for the preparation of diversely functionalized tetrahydroxanthones is based on a trienamine‐mediated cycloaddition between 2,4‐dieneals and activated chromones. It is possibile to control the stereochemical outcome of such reactions by employing an H‐bond‐directing aminocatalyst.
