| titleOfInvention | Method of separating stereoisomers of dicarboxylic acid having norbornene or norbornane structure, or derivative thereof |
| abstract | A method of efficiently extracting a high-purity stereoisomer from a mixture comprising the endo isomer and the exo isomer of a dicarboxylic acid having a norbornene or norbornane structure, or a derivative thereof. The present invention relates to a method of separating the endo isomer and the exo isomer of a dicarboxylic acid represented by a general formula (1) or (2) or a derivative thereof, and includes the step of stirring and mixing a mixture comprising mainly the endo isomer of the dicarboxylic acid represented by the general formula (1) or (2) or a derivative thereof, and the exo isomer of the dicarboxylic acid represented by the general formula (1) or (2) or a derivative thereof, with a basic compound and a solvent. n n n(wherein, R 1 to R 8 represent a hydrogen atom, methyl group, ethyl group, or butyl group), n n n(wherein, R′ 1 to R′ 10 represent a hydrogen atom, methyl group, ethyl group, or butyl group) |
