Reaction Steps
Ethyl 2,3-O-Dibenzoyl-4-O-benzyl-1-thio-β-D-glucohexopyranoside (hdo—9:1) (200 mg, 0.38 mmol) was dissolved in an ice-cooled mixture of pyridine and acetic anhydride (1:1, 6 ml). The mixture was stirred and attained room temperature overnight. The mixture was diluted with dichloromethane and washed with saturated aqueous sodium hydrogen carbonate and water, dried over sodium sulphate the solvents were removed under reduced pressure and the residue was subjected to flash chromatography on silica gel (toluene-acetonitrile 6:1) to yield 204 mg, 93% of hdo—9:2.
