The mechanism of the sulfuric acid-catalyzed acetolysis of methyl 2,3,5-tri-O-acetyl- and methyl 2,3,5-tri-O-benzoyl-Lribofuranosides and the accompanying anomerization of both the starting material and the 1,2,3,5-tetra-O-acetyl- and 1-O-acetyl-2,3,5-tri-O-benzoyl-L-ribofuranoses formed was investigated. The progress of the reactions was followed by 1H NMR spectroscopy and the rate constants for the reactions were determined for a proposed kinetic model. The role of H+ and Ac + as the catalytically active species was clarified, proving that the anomerization of the acylated methyl furanosides is activated by protonation, while, on the contrary, the anomerization of the 1-O-acetyl ribofuranoses is activated by the acetyl cation. The anomerization of the acylated methyl furanosides was verified to be activated on the ring oxygen leading to endocyclic CO-bond rupture while the 1O-acetyl ribofuranoses are activated on the acetyloxy group on C(1) leading to exocyclic cleavage.

An object of the present invention is to provide a industrially appropriate method for producing the β-anomers of ribofuranose derivatives in a highly selective manner at a high yield. The present invention provides a method for producing ribofuranose derivatives wherein β-anomers is precipitated from among the generated furanose derivatives by controlling the amount of a reaction reagent used and/or using a poor solvent in the acetolysis reactions of 2,3,5-tri-O-acyl-1-O-alkyl-ribofuranose and 2,3-di-O-acyl-1-O-alkyl-5-deoxy-ribofuranose.
