Oxidative coupling reactions of the stereochemically defined S-tetrahydroxybinaphthalene derivative gave a separable mixture of two diastereomers of the quaternaphthalenes of S, S, S and S, R, S configurations, whose stereostructures were confirmed by an alternative chemical transformation through the ternaphthalenes as well as the X-ray structure analysis. The CD spectra of the corresponding diastereomers were indicative of the stereochemistry across the axis.
