Crystalline 2-O-alpha-D-mannopyranosyl-beta-D-mannopyranose octaacetate was synthesized by condensation of tetra-O-acetyl-alpha-D-mannopyranosyl bromide (3) with 1,3,4,6-tetra-O-acetyl-beta-D-mannopyranose. 6-O-alpha-D-Mannopyranosyl-alpha-D-mannopyranose octaacetate was prepared by condensation of 3 with 1,2,3,4-tetra-O-acetyl-6-O-trityl-alpha-D-mannopyranose. Fusion of each mannobiosyl octaacetate with p-nitrophenol was followed by deacetylation, to give the corresponding p-nitrophenyl (1 to 2) and (1 to 6)-alpha-D-mannobioside.
通过四 - O - 乙酰基 - α - D - 吡喃甘露糖基溴（3）与1,3,4,6 - 四 - O - 乙酰基 - β - D - 吡喃甘露糖缩合合成了结晶状的2 - O - α - D - 吡喃甘露糖基 - β - D - 吡喃甘露糖八乙酸酯。通过3与1,2,3,4 - 四 - O - 乙酰基 - 6 - O - 三苯甲基 - α - D - 吡喃甘露糖缩合制备了6 - O - α - D - 吡喃甘露糖基 - α - D - 吡喃甘露糖八乙酸酯。将每种甘露二糖基八乙酸酯与对硝基苯酚熔融，然后进行脱乙酰化反应，得到相应的对硝基苯基（1→2）和（1→6）-α - D - 甘露二糖苷。
