TL;DR: In this article, the synthesis of 2-deoxy-2-iodo-glycosylamides, glycosylurea, Nglycosylbenzotriazole, and N-glyco-imidazole by addition reaction of trimethylsilyl amides, imidazoles, and benzotitriazoles to D-glucal at 0 °C.

TL;DR: NaHSO(4) supported on silica gel catalyses the Ferrier rearrangement reaction of 3,4,6-tri-O-acetyl-D-glucal with alcohols and thiols to give the corresponding 2,3-unsaturated glycosides in high anomeric selectivity and good to excellent yield in short reaction time.

TL;DR: In this paper, a combination of glucal with aliphatic aldehydes leads to liquid crystals showing a monotropic SA phase, with aromatic p-alkoxy-substituted aldehyde to compounds with enantiotropic cholesteric and SA phases.
Abstract: Reaction of glucal 1 with alkoxybenzene leads after hydrogenation and deacetylation to β-C glycosides 4, which can be used as chiral compounds in the synthesis of chiral calamitic liquid crystals. The combination with aliphatic aldehydes leads to liquid crystals 5 showing a monotropic SA phase, with aromatic p-alkoxy-substituted aldehydes to compounds 6 with enantiotropic cholesteric and SA phases. Reaction with p-alkoxy-substituted phenylboronic acids gives liquid crystals 7 forming SA and ferroelectric SC* phases. They all exhibit a high twisting power and blue phases in contact preparation.
