Serving up an ace! The first regio‐ and enantioselective version of a chromium‐catalyzed homoallenylation of an aldehyde is described by P. J. Guiry and co‐workers in their Communication on page 9152 ff. The non‐ C 2 ‐symmetric bis(oxazoline) ligand (tennis racket) interacts with the Cr–diene complex (ball), which approaches the aldehyde (net) from the Re face to afford valuable chiral β‐allenols. The Cr–homoallene complex remains out of the game!
