ResumoThe enantioselective synthesis of polycyclic aromatic hydrocarbon (PAH)-based planar chiral cyclophanes was achieved by the rhodium-catalyzed intramolecular [2+2+2] cycloaddition of tethered diyne-benzofulvenes followed by stepwise oxidation. “Mitsudomoe (three comma-shaped figures in a circle, one of the traditional Japanese patterns)”, in which there are left- and right-handed types, represents the catalytic cycle of the enantioselective cycloaddition. The background hydrangea that consists of dense panels expresses the PAH moiety of the cyclophane. More information can be found in the Full Paper by K. Tanaka et al. on page 12579.
