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 ef

✦ Synopsis
The contribution of deuterium to the sign and magnitude of rotation of chiral cyclic ketones has been of continuing interest I,2,3 since early studies by Djerassi and coworkers indicated an anti octant behavior for the isotope. The availability in our laboratory 394 of optically active

## Abstract Starting from cholesterol the three possible stereoisomeric 1,4‐benzodioxanes 24, 31, 32 and a series of analogues with 2βH,3βH configuration (25–27, 29, 30) have been synthesized. The α band of the 1,4‐benzodioxane chrompohore has been unequivocally identified in the CD spectra between
