A simple and efficient method for the preparation of 2-O-beta-D-ribofuranosylnucleosides, minor tRNA components, is described in this unit. The method consists of condensation of a small excess of 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-D-ribofuranose activated with tin tetrachloride with N-protected 3,5-O-tetra-isopropyldisiloxane-1,3-diyl-ribonucleosides in 1,2-dichloroethane. Subsequent deprotection produces 2-O-beta-D-ribofuranosylnucleosides in an overall yield of 46% to 72%.
