[Application]

Beta-D-Ribofuranose 1-acetate 2,3,5-tribenzoate, also known as 1-O-Acetyl-2,3,5-tri-O-benzoyl-beta-D-ribofuranose, is a ribose-derived compound used in nucleoside synthesis.
[Definition]

The commonly used 1-O-acetyl-2,3,5- tri-O-benzoyl-β-D-ribofuranose (beta-D-Ribofuranose 1-acetate 2,3,5-tribenzoate) can be employed in the glycosylation of 7-deazapurines when 7-halogenated nucleobases are used. Using common ribosugars such as 1-O-acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose resulted in the formation of orthoamides when the pyrrole ring was not functionalized. The glycosylation yield and glycosylation position of 7-deazapurines with 1-O-acetyl-2,3,5-tri-O-benzoyl-β-D-ribofuranose depends strongly on 7-substituents (H vs halogen) and amino protecting groups. It could be used to synthesize 5-Bromo-4-chloro-2-[(N2-isobutyryl){2,3,5-tri-O-benzoyl-β-Dribofuranosyl}]amino-7H-pyrrolo[2,3-d]pyrimidine.
[Synthesis]

Rac-(2R,3R,4R,5R)-2-((benzoyloxy)methyl)-5-hydroxytetrahydrofuran-3,4-diyl dibenzoate was dissolved in dry pyridine, and the solution was slowly added dropwise with acetic anhydride in an ice water bath, then stirred for 30 minutes. Then, the ice water bath was removed, and the solution was stirred at room temperature for 7 hours and then heated to 40°C. This temperature was kept for an hour. The solution was added with broken ice and then stirred until the broken ice melted. The reaction solution was poured into ice water and extracted with chloroform. The organic layer was washed sequentially with ice water, pre-cooled sulfuric acid, and saturated sodium bicarbonate until the water layer showed weak alkaline, then washed with ice water until the water layer showed neutral, dried over anhydrous sodium sulfate for more than 4 hours, and then drawn off under reduced pressure, to obtain the light yellow syrup-like beta-D-Ribofuranose 1-acetate 2,3,5-tribenzoate (92.1%).
