Синтез анизотропных соединений

Abstract

Continuing our interest in the intermediates for the preparation of liquid-crystalline and anisotropic compounds for different practical application, we summarize and show here how the advanced both nonchiral and chiral nematic, smectic and other anisotropic compounds can be successfully synthesized by the transformations of the available 3,6-disubstituted cyclohex-2-enones, 3,5-disubstitiuted 2-isoxazolines, 1,2-disubstitiuted cyclopropanoles, substituted epoxyketones. It have been shown that different reaction possibilities for the functional groups in the central core or at the terminal position, and cyclohexenone, isoxazoline, cyclopropanol or epoxyketone fragments; diversity of the variants of the modification of these intermediates under the influence of different chemical reagents and reaction conditions allow the transformations to be achieved selectively and give the opportunity of preparing mesomorphic and anisotropic compounds with novel combinations of the structural fragments of molecules.
