Participants

Reaction Steps

[C] 25 g of 1,6-anhydro-2-acetyl-3,4-dideoxy-β-D-galactopyranose (6), obtained in the step [B] was dissolved in 100 ml of methanol, forming a solution. A small amount of sodium methoxide was added to the solution. The solution was stirred for one hour at room temperature, causing a reaction therein. Upon the completion the reaction, cation exchange resin was added to the solution, and the solution was stirred for 10 minutes. The insoluble substance was filtered off, and the solvent was distilled off under reduced pressure, whereby 19 g of 1,6-anhydro-3,4-dideoxy-β-D-galactopyranose (7) was obtained at a yield of 100%. This substance exhibited the following physical properties:
