An Efficient Approach to the Synthesis of Nucleosides: Gold(I)‐Catalyzed N‐Glycosylation of Pyrimidines and Purines with Glycosyl <i>ortho</i>‐Alkynyl Benzoates

Abstract

Persuaded with gold: The title reaction in the presence of [Ph3PAuNTf2] (Tf=trifluoromethanesulfonyl) led conveniently to the corresponding nucleosides with excellent regioselectivity (see scheme). Even purine derivatives underwent this transformation owing to the mild conditions, which enabled the use of protecting groups that would not usually be compatible with N-glycosylation conditions.
