| titleOfInvention | Optically active ethanol derivative and production thereof |
| abstract | NEW MATERIAL:The optically active ethanol derivative of formula I (A is H, lower alkyl, lower alkoxy or halogen; Z is H or halogen; l is 0 or 1; *represents asymmetric C). EXAMPLE:(+)-4-Benzyloxy-1-phenethyl alcohol. USE:An intermediate for a liquid crystal material, especially a ferroelectric liquid crystal material having excellent stability and quick response and an intermediate for agricultural chemicals and pharmaceuticals, etc. PREPARATION:Ether one of optical active compounds of formula I can be produced by mixing (A) dl-esters of formula II (R' is lower alkyl) with (B) an esterase capable of hydrolyzing either one of the enantiomers of the above esters, e.g., an enzyme (such as lipase) originated from animals, vegetables or microorganisms, and vigorously agitating the mixture in a buffer solution (e.g. phosphate buffer solution) at 10-60 deg.C for 10-70hr to effect asymmetric hydrolysis. The unreacted ester is further hydrolyzed to obtain the other compound of formula I which is the antipod of the above compound. |
