Rounding up: A RhI‐catalyzed intermolecular cycloaddition of 4‐allenals with alkynes has been developed that provides various monocyclic eight‐membered rings in good to high yields in a stereoselective manner (see scheme). In addition, the chirality of the starting allene is transferred in this reaction, thereby giving optically active monocyclic eight‐membered ring compounds.
