Reaction Steps

The crude reaction mixture obtained by the procedure described in Example 2 containing 3-S-Acetyl-1,2:5,6-di-O-isopropylidene-3-thio-α-D-allofuranose E2 (7.5 g, 23.58 mmole) was dissolved in methanol and added to a slurry of freshly prepared Raney nickel (prepared from nickel-aluminium alloy, 60 g) in methanol (100 ml). The reaction mixture was stirred at room temperature for 15 h and filtered. The filtrate was concentrated under reduced pressure to give the title product E3; yield: 5 g, 88%, which was subjected to the following step without further purification.
