| titleOfInvention | Production of optically active compound |
| abstract | PURPOSE: To industrially advantageously obtain the subject compound useful for mixture of liquid crystal by esterifying only (R)-matter of specific racemic alcohol and fatty ester of 2,2,2-trichloroethanol, etc., with esterase and separating (S)-matter. n CONSTITUTION: Racemic alcohol expressed by formula I [A is halogen, cyano, methoxy or the formula COOR 1 (R 1 is 1-6C alkyl)] and ester of 2-16C fatty acid of 2,2,2-trichloroethanol or vinyl fatty ester expressed by formula II (R 2 is H or methyl; R 3 is 1-8C alkyl) are affected by enzyme having esterase activity to selectively make only (R)-matter of racemic alcohol to ester compound and separate from alcohol of unreacted (S)-matter to afford the aimed optically active compound. n COPYRIGHT: (C)1990,JPO&Japio |
