The Use of Simple Sugars for the Synthesis of Chiral Monophilic Liquid Crystals

Abstract

Abstract By Ferrier glycosylation of glycals and subsequent hydrogenation 2,3-dideoxyglycosides were obtained. Starting with glucose, xylose or rhamnose this reaction sequence led to thermotropic non-amphiphilic chiral liquid crystals. The synthesized compounds show cholesteric and smectic as well as blue and other cubic phases. The liquid crystalline properties were influenced by the anomeric effect.
