beta-D-Ribofuranose, 1-acetate 2,3,5-tribenzoate

개요β-D-Ribofuranose 1-Acetate 2,3,5-Tribenzoate is an optically active ribose derivative. It is white to orange to green powder to crystals, slightly soluble in methanol, and can be used as a starting material for nucleoside synthesis. The substance is also used as an intermediate for Clofarabine, which belongs to a class of drugs called purine nucleoside antimetabolites and is used to treat acute lymphoblastic leukemia (ALL) in children and young adults aged 1 to 21 years.

용도An inhibitor of neutrophil-keyhole limpet hemocyanin adhesion

정의The 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.
