STEREOSELECTIVE SYNTHESIS OF α-RIBONUCLEOSIDES FROM 1-HYDROXY SUGARS BY USING 2-FLUOROPYRIDINIUM TOSYLATE

A novel method for the preparation of α-ribonucleosides was developed by the use of 2-fluoro-1-methylpyridinium tosylate as a condensing reagent.Various α-ribonucleosides were synthesized from 1-hydroxy sugars and trimethylsilylated nitrogen compounds, such as nucleoside bases and azide, in good yields under mild conditions.

D-RIBOFURANOSYL AZIDES. A DIRECT CONVERSION OF 1-O-ACYL-2,3-O-ISOPROPYLIDENE-D-RIBOFURANOSE INTO D-RIBOFURANOSYL AZIDES

Reactions of azidotrimethylsilane with 1-O-acetyl-2,3,5-tri-o-benzoyl-β-D-ribofuranose (2), and the 1,5-di-O-p-nitrobenzoyl and 1,5-di-O-acetyl derivatives, 4 and 5 respectively, of 2,3-O-isopropylidene-β-D-ribofuranose, in the presence of the Lewis acids
