| titleOfInvention | Optically active 1-phenylethanol derivative and production thereof |
| abstract | NEW MATERIAL:An optically active 1-phenylethanol derivative expressed by formula I (R is H or acetyl; R' is H, lower alkyl, lower alkoxyl or halogen; mark * indicates asymmetric carbon). n EXAMPLE: Benzyl (-)-4-(1-acetoxyethyl)phenylcarboxylate. n USE: An intermediate for medicines, agricultural chemicals, etc., particularly organic electronic material, especially an intermediate for liquid crystal compounds. n PREPARATION: Ketones expressed by formula II are reduced with a reducing agent to provide alcohols expressed by formula III, which are subsequently reacted with acetic acids to afford dl-esters expressed by formula IV. The resultant dl-esters are then asymmetrically hydrolyzed with an esterase having the ability to hydrolyze either of enantiomers thereof to provide the aimed optically active substance expressed by formula I. n COPYRIGHT: (C)1989,JPO&Japio |
