35 nucleosides were synthesized by coupling thioglycosides with pyrimidines and purines under the preactivation of (p-Tol)2SO/Tf2O in high yields and with β-stereoselectivities.

Glycosyl trifluoroacetimidates have been disclosed to be effective glycosyl donors for the synthesis of nucleosides; the present N-glycosylation protocol requires only a catalytic amount of TMSOTf as promoter and proceeds smoothly at room temperature. (c) 2008 Elsevier Ltd. All rights reserved.
