| titleOfInvention | Optically active carboxylic acid derivative and production thereof |
| abstract | NEW MATERIAL:An optically active carboxylic acid derivative expressed by formula I (l is 1 or 2; mark * indicates asymmetric carbon). n EXAMPLE: (+)-4-(1-Hydroxyethyl)benzoic acid. n USE: An intermediate for agricultural chemicals, medicines and veterinary drugs, especially for ferroelectric liquid crystal compounds. n PREPARATION: Optically active esters expressed by formula II (R is H or R"CO; R' and R" are lower alkyl) are hydrolyzed or esters expressed by formula III are asymmetrically hydrolyzed with an esterase having the ability to hydrolyze only either of enantiomers to afford the aimed optically active substance expressed by formula I. Furthermore, the above-mentioned compound can be converted into a liquid crystal compound, excellent as ferroelectric liquid crystal and expressed by formula IV (R 1 and R 2 are alkyl or acyl; Ar is aromatic group, cyclic saturated group, etc.). n COPYRIGHT: (C)1989,JPO&Japio |
