Intermolecular [2 + 2 2] cycloaddition of 1-alkynyl-8-arylnaphthalenes with 1,6-diynes proceeded in the presence Rh-chiral BINAP derivative catalysts to give axially chiral 1,8-diarylnaphthalenes excellent yields along up perfect enantioselectivity. As aryl moiety, we could introduce 1-pyrenyl and (dibenzo)carbazolyl groups addition substituted phenyl ones. 1-Aryl-8-(1-pyrenyl)naphthalenes exhibited high fluorescence quantum (up Φ = 0.89) circularly polarized luminescence (CPL) properties (|glum| 1.6 × 10-3).
