    • Typical Experimental Procedure: Ammonium acetate (0.3 g, 4.0 mmol) was added into a stirred solution of α-D-mannopyranose peracetate 1c (0.8 g, 2.0 mmol) in anhydrous DMF (3 mL, The resulting mixture was stirred at ambient temperature overnight. The solvent was removed under reduced pressure and the residue was purified by flash chromatography (hexane/ethyl acetate) to afford the desired 2,3,4,6-tetra-O-acetyl-D-mannopyranose 2c: 0.7 g (98, All the products except 2h are known compounds.
