## Abstract Alkyl 1‐thio‐α,β‐D‐glucopyranosides (hexyl to decyl, 1a–e) are prepared by reaction of penta‐__O__‐acetyl‐β‐D‐glucopyranose with the respective thiols in the presence of diethyl ether — trifluoroborane, followed by deacetylation. 1a–e are converted into their tetra‐__O__‐diethylboryl de
Synthesis, Purification and Liquid-Crystalline Behavior of Several Alkyl 1-Thio-D-glycopyranosides. -The synthesis of the title compounds is achieved via Lewis acid mediated coupling of the fully acetylated monosaccharide with the appropriate alkanethiol. The choice of the Lewis acid depends on the
