| titleOfInvention | Production of optically active benzene derivative |
| abstract | NEW MATERIAL:An optically active benzene derivative shown by formula I (R is 1W20C alkyl or alkoxyalkyl; A is H, lower alkyl, lower alkoxy or halogen; n is 1 or 2; * is asymmetric carbon). n EXAMPLE: (+)-4-(1-S-2'-Methylbutoxyethyl)benzoic acid. n USE: Useful as an intermediate for agricultural chemicals, drugs, etc. and also suitable as an intermediate for liquid crystal compounds. n PREPARATION: An optical active ether derivative shown by formula II (A is H, lower alkyl, lower alkoxy or halogen) is debenzylated to give a compound shown by formula I. The debenzylation reaction is usually carried out by catalytically hydrogenating with hydrogen in the presence of a hydrogenating catalyst or hydrolysis. The amount of the catalyst used is preferably 0.05W0.3pt.wt. based on 1pt.wt. compound shown by formula II. The reaction is carried out preferably at 10°CW60°C. n COPYRIGHT: (C)1989,JPO&Japio |
