with indium(III) bromide in chloroform;Reflux;

Steps:

10

General procedure: Peracetyl-β-D-glycopyranose (1-5, 10mmol), InBr₃ (106mg, 0.3mmol, 0.03eq), and alkane-1-thiol (20mmol, 2eq) were suspended in CHCl₃ (7mL). The reaction mixture was heated to reflux with magnetic stirring. The course of the reaction was followed by TLC (hexane:EtOAc 1:1). After 1 hour the peracetate starting material could no longer be detected by TLC. The reaction was cooled to RT, diluted with CH₂Cl₂ (20mL), and this solution was applied to a short column (4cm×12cm) of SiO₂. The HOAc that was formed from the reaction and the excess alkane-1-thiol were eluted with hexanes. The desired thio-glycoside peracetate was eluted with hexanes:EtOAc 7:3. The fractions containing the desired material were combined, concentrated in vacuo, and the intermediate peracetates (12-14, 16-28) were characterized by 1D, 2D, ¹H-NMR and ¹³CNMR in CDCl₃ (in Tables in Supplementary data)
