The invention also relates to chiral linear or crosslinked liquid crystalline polymers obtainable by polymerizing a polymerizable mixture comprising at least one chiral compound of formula I, and to the use of chiral compounds of formula I and mixtures and polymers obtained thereof in liquid crystal displays, such as STN, TN, AMD-TN, temperature compensation, guest-host, phase change or surface stabilized or polymer stabilized cholesteric texture (SSCT, PSCT) displays, in active and passive optical elements like polarizers, compensators, alignment layers, color filters or holographic elements in adhesives, synthetic resins with anisotropic mechanical properties, cosmetics, diagnostics, liquid crystal pigments, for decorative and security applications, in nonlinear optics, optical information storage or as chiral dopants, and to a liquid crystal display comprising a mixture comprising at least one chiral compound of formula I.

SYNTHESIS OF THREO-3-ARYL-2,3-DIHYDROXYPROPANOIC ACID DERIVATIVES WITH HIGH OPTICAL PURITY

Cyanohydrins of arylaldehides can be obtained in high optical purity using the'Inoue' dipeptide catalyst system and converted into enantiomerically and diastereochemically pure threo-3-aryl-2,3-dihydroxypropanoic acid derivatives using a route which involves a novel base-catalysed equilibration of the acetonides of the cyanodiols.
