摘要：
An optically active pyrimidine compound represented by general formula (I): ##STR1## wherein R represents a fluoroalkyl group having 1 or 2 carbon atom(s), R.sup.1 represents an alkyl group having 1-15 carbon atoms or an alkoxyalkyl group having 2-15 carbon atoms, both the alkyl and alkoxyalkyl groups being optionally substituted by halogen atom, Y represents --O--, --COO-- or --OCO--, A represents: ##STR2## wherein X represents a hydrogen atom or a halogen atom, m and s each represent 0 or 1, and the C* means an asymmetric carbon atom; a process for producing said pyrimidine compound; and a liquid crystal composition containing said pyrimidine compound.
