A new comprehensive drug synthesis experiment was introduced in this article. From commercially available D-mannose, methyl 2, 3, 4, 6-tetra-O-benzoyl-α-D-mannopyrannoside was synthesized via Fischer-Helferich glycosylation followed by benzoylation. The intermediate and the target compound were purified by filtration, washing, concentration, extraction, drying, and silicon column separation. The structure was characterized by the infrared spectrum (IR), nuclear magnetic resonance (NMR) spectrum, measurements of melt point and optical rotation of the compound.

Key words: Reactionmonitoring, D-mannose, Structural characterization, Drug synthesis experiment
