| titleOfInvention | Process for production of optically active carboxylic acid |
| abstract | The invention provides a process for production of optically active 2,2-dimethylcyclopropanecarboxylic acid by reacting an optical isomer mixture of 2,2-dimethylcyclo- propanecarboxylic acid with an optically inactive amine to form (precipitate or crystallize) an ammonium salt of optically active 2,2-dimethylcyclopropanecarboxylic acid, e.g., optically active (S)-(+)-2,2-dimethylcyclopropanecarboxylic acid. According to the invention, the production (including optical resolution, separation of optical isomers, and purification of optical isomers) of optically active 2,2-dimethylcyclopropanecarboxylic acid important as an intermediate in the production of agricultural chemicals and drugs can be easily carried out at a low cost. Further, the invention provides intermediates for the above production (e.g., ammonium salts of optically active 2,2-dimethylcyclopropanecarboxylic acid, particularly, ammonium salts of optically active (S)-(+)-2,2-dimethyl- cyclopropanecarboxylic acid) and reagents for optical resolution for the separation of optically active 2,2- dimethylcyclopropanecarboxylic acid (e.g., optically inactive amines). |
