(S,R,S,R,S,R,S)- and (S,R,S,S,S,R,S)-octinaphthalenes were synthesized by oxidative coupling of (S,R,S)-quaternaphthalene, and differences due to axis chirality of (S,R,S,R,S,R,S)-, (S,R,S,S,S,R,S)-, (S,S,S,R,S,S,S)-, and (S,S,S,S,S,S,S)-octinaphthalenes were compared using the Rf values on TLC, specific optical rotations, 1H NMR chemical shifts of the hydroxy groups, and CD spectra. A clear CD additivity was found in the Δε values of the 1La transition around 290 nm, which are proportional to the difference between the numbers of S and R binaphthalene units.
