Abstract
NEW MATERIAL:An optically active compound expressed by formula I (R represents 6-16C straight chain alkyl; n is 1 or 0; * indicates asymmetric carbon atom.). EXAMPLE:A compound expressed by formula II. USE:A liquid crystal compound used as an electric display material which exhibits sufficient chiral smectic C phase at about ambient temperature. PREPARATION:A compound expressed by formula III is reacted with a compound expressed by formula IV with dehydration in a solvent such as dichloroethane, dichloroethane or carbon tetrachloride in the presence of a dehydrating agent (preferably N,N'-dicyclohexylcarbodiimide) preferably in an equimolar amount (based on the formula IV) and further in the presence of pyridine.
