The invention relates to the field of organic synthesis, in particular to a method for preparing 1-O-acetyl-2, 3, 5-tri-O-benzoyl-1-beta-D-ribofuranose, which comprises the following steps: mixing D-ribose with methanol and a catalyst, heating to react, neutralizing, and concentrating to obtain a methyl esterification intermediate III; mixing the methyl esterification intermediate III with an organic solvent, 4-dimethylaminopyridine and an acid-binding agent, cooling, dropwise adding benzoyl chloride for reaction, washing with water for layering, and drying to obtain a benzoylated intermediateII; finally, mixing the benzoylated intermediate II with an organic solvent and acetic anhydride, then adding a catalyst, stirring, carrying out heat preservation reaction for 10-20 hours at the temperature of 0-70 DEG C, and after the reaction is qualified, cooling, crystallizing and centrifuging to obtain a crude product; finally, performing recrystallization and centrifugal drying to obtain the 1-O-acetyl-2, 3, 5-tri-O-benzoyl-1-beta-D-ribofuranose, and obtaining the 1-O-acetyl-2, 3, 5-tri-O-benzoyl-1-beta-D-ribofuranose. The method has the advantages of short reaction steps, high chemicaland optical purity, simple operation, easily available raw materials, low cost, small amount of three wastes, environmental friendliness and the like, and is suitable for industrial production.
