| titleOfInvention | Method for producing optically active carboxylic acid, method for producing liquid crystal compound, method for producing highly pure optically active amino acid, and optically active carboxylic acid amide and optically active carboxylic acid |
| abstract | (57) [Summary] (Modified) [Objective] To provide an optically active carboxylic acid and a method for producing the same. A racemic carboxylic acid of general formula I * or formula II * is reacted with an optically active 2-aminocarboxylic acid ester to form a diastereomer of a carboxylic acid amide of formula IV * or formula V * , A method for producing an optically active carboxylic acid, in which the diastereomer is separated, and then the amide bond is cleaved to isolate the optically active compound of the general formula I * or the formula * Optically active compounds of * , II * , IV * and V * , the general formula I * Or II * preparation of the liquid crystal compounds using optically active carboxylic acids of the general formula I * or II * utilizing optically active carboxylic acids, process for producing a high purity of the optically active amino acids.
