PROCEDURE
实验过程
Methyl 4-O-(2,3,6-tri-O-benzyl-4-deoxy-4-acetyloxymethy-α-D-glucopyranosyl)-2,3,6-tri-O-benzyl-α-D-glucopyranoside (3.19 g, 3.35 mmol) is dissolved in hot toluene (20 mL) and methanol (80 mL) is added, followed by a few drops of 1 M. methanolic sodium methoxide. The mixture is stirred at room temperature during 2 h. The reaction mixture is made neutral with Amberlite IR 120 (H+) resin, filtered and concentrated under reduced pressure so as to afford methyl 4-O-(2,3,6-tri-O-benzyl-4-deoxy-4-hydroxymethyl-α-D-glucopyranosyl)-2,3,6-tri-O-benzyl-α-D-glucopyranoside as an amorphous solid.
