Application of a novel chromophoric reagent, 2,2′-binaphthyl-3,3′-dicarbonyl cyanide, to the absolute configuration determination of chiral secondary alcohols
3′-dicarbonyl cyanide possessing two reaction sites was designed and synthesized as a new chromophoric reagent for exciton-coupled circular dichroism (ECCD), which is more effective in determination of the absolute stereochemistry of the target chiral alcohols than 2,2′-binaphthyl-3-methoxycarbonyl-3′-carbonyl cyanide, which contains only one reaction site. The CD spectra of the 2,2′-binaphthyl diesters
