Trityl Salt Catalyzed Stereoselective Glycosylation of Alcohols with 1-Hydroxyribofuranose

Abstract In the presence of a catalytic amount of several trityl salts, 2,3,5-tri-O-benzyl-d-ribofuranose smoothly reacted with alcohols to give various β-ribofuranosides in high yields with high stereoselectivity while reversed stereoselectivity was observed in the coexistence of lithium perchlolate.
