Starting with (R)-1,2-epoxyalkanes, (S)-5-alkyl(or -alkyloxy)-2-[4-(3-fluoroalkyl)phenyl]pyrimidines and (S)-5-(3-fluoroalkyl)-2-(4-alkyloxyphenyl)pyrimidines were synthesized and shown to be good chiral dopants for achieving fast response of ferroelectric liquid crystals mixtures.

The title ethers, expected chiral dopants for ferroelectric liquid crystals, were prepared by the allylation of chiral cyanohydrins under the acidic conditions followed by hydrogenation, or alternatively by the Johnson's cyanation of chiral acetals followed by fluorination.

Optically active 2-alkyl-1-aryl-1-cyanocyclopropanes were synthesized from 2-aryl-4-hydroxyalkanenitriles which in turn were obtained by the reaction of chiral 1,2-epoxyalkanes with the carbanions derived from arylacetonitriles.

O-Acyl cyanohydrins having a chiral center directly connected to the core aromatic ring were prepared through asymmetric hydrocyanation of 4-substituted benzaldehydes and shown to be excellent chiral dopants for ferroelectric liquid crystals.

Optically active α-aryl-γ-alkyl-γ-lactones were synthesized through the reaction of chiral 1,2-epoxyalkanes with the carbanion derived from 4-methoxyphenylacetonitrile or 4-methoxyphenylacetic acid and shown to be good chiral dopants for ferroelectric liquid crystals.

New chiral dopants for ferroelectric liquid crystals containing an optically active oxazolidin-2-one moiety, synthesized from (R)-1,2-epoxyoctane, exhibit large spontaneous polarization.

Starting with (S)-1-chloro-2,3-epoxypropane optically active cyanocyclopropanes and cis-γ-lactones having a trialkylsilyl group in an alkyl side chain were synthesized and ferroelectric liquid crystals mixture containing one of these as a chiral dopant exhibited large spontaneous polarization.

Chiral alkylsulfinylbenzenes having an ester functional group at C-4 were prepared and shown for the first time to be ferroelectric liquid crystals and excellent chiral dopants for them.

The title compounds were prepared through asymmetric reductions and derivatized into the ester compounds which were shown to be potent chiral dopants for ferroelectric liquid crystal materials.
