Abstract
A mild and highly efficient method has been developed for the deprotection of 1,1-diacetates using a catalytic amount of indium tribromide immobilised in 1-butyl-3-methylimidazolium hexafluorophosphate as an ionic liquid. This affords the corresponding the parent aldehydes in excellent yields. The recovered ionic liquid containing catalyst has been recycled in three subsequent runs.

Abstract
Acetal, trityl, and TBDMS protecting groups on saccharides were subjected to alcoholysis using a catalytic amount of vanadyl triflate in an MeOH-CH2Cl2 solvent system. The configuration at the anomeric positions of saccharides was retained, and no glycosidic bond cleavage and oxidation of sulfides were observed. The presented method was easily implemented, compatible with diverse functional groups, and regioselective in some cases.
