• Beschreibung

  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.

• Verwenden

  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].
