Abstract 1,2-Migration and concurrent glycosidation of ethyl(phenyl) 2,3-orthoester-1-thio-α- d- and l -mannopyranosides under the action of TMSOTf readily afforded the corresponding 2- S -ethyl(phenyl)-2-thio-β-glucopyranosides, ready precursors to 2-deoxy- arabino -hexopyranosides (2-deoxy-β-glucopyranosides).

As a consequence of the exo-anomeric effect, and in contrast to their β-anomers, α-thioglycosides undergo stereoselective oxidation to give very predominantly the R-sulfoxides, as revealed by X-ray crystallography.
X 射线晶体学显示,由于外异构体效应,与δ-异构体不同,δ-硫代糖苷会发生立体选择性氧化,主要生成 R-硫醚。
