Abstract

NEW MATERIAL:An optically active compound expressed by formula I (X is formulas II, III, IV, V, etc.; n is 0 or a positive integer).
EXAMPLE: The compound of formula VI.
USE: An additive capable of being added to a liquid crystal without reducing the point thereof extremely, and giving a stable liquid crystalline composition having a short pitch. Usable as an orientation improver for a TN cell or an optical rotatory power imparting agnet capable of changing a nematic liquid crystal into a cholesteric liquid crystalline composition causing selective reflection in the visible region.
PROCESS: l-Menthol is esterified with an acid chloride which is a raw material for an ester liquid crystal in a suitable solvent, e.g. ether, in the presence of a base, e.g. pyridine, to give the compound of formula I.
