Procedure

A solution of 5-C-(acetoxymethyl)-1,2,3,4,6-penta-O-acetyl-L-arabino-hexopyranose (7) (4.0 g, 8.7 mmol) in 0.05M methanolic sodium methoxide (50.0 ml) is stirred at room temperature for 2 hours. The reaction mixture is deionized with Amberlite IR-120 (H+) and evaporated to oily residue. Purification on a silica column with chloroform:methanol (4:1) followed by chloroform:methanol (3:2) gives 0.5 g (27%) of (8).
