✦ Synopsis

Enantiopure 1,1Ј:4Ј,1Љ-ternaphthalene compounds were synthesized via enantioresolution of 1,1Ј:4Ј,1Љ-ternaphthalene-2,2Љ-dimethanol (2) by the chiral phthalic acid amide method. The CD spectra of chiral 1,1Ј:4Ј,1Љ-ternaphthalene compounds synthesized showed typical intense exciton split CD Cotton effects, from which the absolute stereochemistry of these 1,1Ј:4Ј,1Љ-ternaphthalene compounds was unambiguously determined by the CD exciton chirality method.
