PARTIAL ASYMMETRIC SYNTHESIS OF ATROPISOMERIC 1,1'-BINAPHTHYLS VIA THE ULLMANN COUPLING REACTION OF CHIRAL ALCOHOL ESTERS OF 1-BROMO-2-NAPHTHOIC ACID

Miyano, Sotaro,Tobita, Masayuki,Suzuki, Shoji,Nishikawa, Yukio,Hashimoto, Harukichi

, p. 1027 - 1030 (1980)

The Ullmann coupling of 1-bromo-2-naphthoates of C-chiral alcohols of R- and S-configuration induced axial dissymmetry of R- and S-chirality, respctively, in the newly formed 1,1'-bond of the binaphthyls; the optical yield amounted up to 13percent where the chiral alcohol was l-menthol.
