Abstract
Lithium bis[(trifluoromethyl)sulfonyl]imide was found to be a new and effective additive in the stereocontrolled synthesis of α-D-ribofuranosides from 2,3,5-tri-O-benzyl-D-ribofuranose and several alcohols while β-anomers were formed in the absence of the lithium salt. A hypothetical mechanism of this reverse stereocontrol to yield α-D-ribofuranosides by the influence of the lithium salt is discussed.
