Description
beta-D-Ribofuranose 1,2,3,5-tetraacetate is an acetylated derivative of ribose extensively used in carbohydrate research and synthetic chemistry. This compound features acetyl groups protecting the hydroxyl functionalities at positions 1, 2, 3, and 5 of the ribofuranose ring, which enhances its stability and solubility in organic solvents. β-D-Ribofuranose 1,2,3,5-tetraacetate is a crucial intermediate in synthesising nucleosides, nucleotides, and other complex carbohydrates. In research, it is utilized to study glycosylation mechanisms, focusing on the formation and stereochemistry of glycosidic bonds.
Chemical Properties
beta-D-Ribofuranose 1,2,3,5-tetraacetate is white to almost white crystalline powder
Uses
beta-D-Ribofuranose 1,2,3,5-tetraacetate is used in the synthesis of 3-(β-D-ribofuranosyl)-2,3-dihydro-6H-1,3-oxazine-2,6-dione, a new pyrimidine nucleoside analog related to uridine.
Application
beta-D-Ribofuranose 1,2,3,5-tetraacetate, also known as 1,2,3,5-tetra-O-Acetyl-beta-D-ribofuranose (TAR), is an important organic reagent that can be used in the following pathways:
(1) Used in low-energy electron-induced reactions in gas-phase TAR. Since the acetyl group in TAR is coupled to the five-membered ribose ring at relevant positions, it can serve as a suitable model compound for studying the reaction of sugar units in DNA to low-energy electrons[1].
(2) Used to prepare 1,2,3-tri-O-acetyl-β-d-ribofuranose by enzymatic deacetylation[2].
(3) Used in condensation reactions. In the presence of tin chloride, 1-hexene reacts with 1- O -acetyl-2,3,5-tri- O -benzoyl-β- d -ribofuranose ( 5b ) or 1,2,3,5-tetra- O -acetyl-β- d -ribofuranose ( 5a ) to form a complex mixture[3].
