Abstract
NEW MATERIAL:An optically active benzene derivative of formula I (R is 1-20C alkyl which may contain halogen atoms, alkoxyalkyl; Z is H, halogen). EXAMPLE:(+)-4-(1'-Propoxyethyl)phenol. USE:It is useful as an intermediate of medicines and agrochemicals, especially used as a liquid crystal material. PREPARATION:An optically active ether derivative of formula II (A is H, lower alkyl, lower alkoxy, halogen; * is asymmetric carbon atom) is subjected to debenzylation to give the compound of formula I. The compound of formula II is obtained by condensation reaction of an optically active alcohol of formula III with an alkylating agent of formula IV (X is halogen, -OSO2R''; R'' is lower alkyl, substituted phenyl).
