We report the synthesis of a [20]cyclophenacene‐type cyclophenylene‐naphthylene (CPN) belt and the enantioselective synthesis of chiral‐type CPN belts (up to >99 % ee) by the cationic rhodium(I)‐catalyzed intramolecular [2+2+2] cycloaddition of naphthalene‐embedded cyclic polyynes. The synthesis...
