摘要： An optically active lactone derivative represented by the following general formula (I):
wherein R¹ represents a straight-chain or branched alkyl, alkoxyl, alkanoyloxy, alkoxycarbonyl, alkoxy­alkyl, alkoxyalkanoyloxy, or alkoxyalkoxyl group having 1 to 20 carbon atoms or an optically active group of each of the above kinds, R² represents a straight-chain or branched alkyl group having 1 to 20 carbon atoms,
and the asymmetric carbon atoms at the 2- and 4-positions in the lactone ring each independently is of the (S) or (R) configuration, an intermediate therefor, a process for producing the intermediate, a liquid-­crystal composition, and a liquid-crystal display device.

摘要： An optically active carboxylic acid derivative represented by the general formula
wherein R represents a normal alkyl group having l to 20 carbon atoms, m and n represent 0 or l but are not l at the same time, X represents a hydrogen or halogen atom, Y represents a hydrogen or fluorine atom, provided that when Y is a hydrogen atom, X is a halogen atom, and that when n is 0, Y is a hydrogen atom, and Q* represents an optically active alkyl or l-alkoxyethyl group having an asymmetric carbon atom.
