Polyfunctional intermediates for the preparation of liquid-crystalline and anisotropic materials

摘要

This paper describes the polyfunctional intermediates for the preparation of various anisotropic and liquid-crystalline compounds with different combinations of cyclic, bridge, terminal fragments and lateral substituents. Both chiral and nonchiral nematic, smectic mesomorphic and anisotropic compounds can be prepared by the transformations of the corresponding 3,6-disubstituted cyclohex-2-enones, trans-2,5-disubstituted cyclohexanones, 3,5-disubstitiuted 2-isoxazolines, substituted cyclohex-2-enonyl 2-isoxazolines, 1,2-disubstitiuted cyclopropanols and substituted unsaturated epoxyketones.
