Reaction Steps
If the procedure described in Preparation V is followed, except that the reaction is carried out at 0° C., starting from 1.5 g (34.10-3 mol) of 2,4-dicyanophenyl 2,3,4-tri-O-acetyl-1,5-dithio-β-D-xylopyranoside (Example 16a), 0.71 g (yield: 67%) of the expected product is obtained after chromatography on silica using a CH2Cl2 /CH3OH mixture (8/1 v/v) as the eluent.
