Abstract
A novel achiral biaryl-type compound and a circular dichroism(CD) color fixing agent are provided. Furthermore, a method for determining an absolute configuration of a chiral compound is carried out by introducing the above achiral biaryl-type compound into the chiral compound.
Claims3
An achiral biaryl-type compound in which the biaryl-type compound is at least one compound selected from 2, 2′-binaphthyl dicarboxylic acid derivative represented by the following general formula (II):
- (wherein R is H, Me-, Et-, i-Pr—, n-Bu-, i-Bu- or t-Bu- and Y is OH—, CN—,
- provided that R is i-Pr—, n-Bu-, i-Bu- or t-Bu- when Y=OH).
