Optically active compound, liquid crystal composition and intermediate for synthesizing the same compound

Abstract

Abstract NEW MATERIAL:A compound shown by formula I (R<1> is 4-22C alkyl or 4-22C alkoxy; X is group shown by formula II-formula VIII (Q is halogen, nitrile or OH); Y is H, OH, halogen, methyl or nitrile; Z is methyl; C* is optically active carbon; m is 0 or 1; n is 0-6). EXAMPLE:4-(4'-Octyloxyphenyl)benzoic acid 3-hydroxy-4-(1-oxo-2-methylbutyl) phenyl. USE:Part required for developing a ferroelectric liquid crystal composition. PREPARATION:An acid halide shown by formula IX, etc., is reacted with an optically active group-containing substituted phenol shown by formula X in the presence of a basic solvent such as pyridine to give a compound shown by formula I.
