Following our discovery that silver(I) oxide-promoted glycosylation with glycosyl bromides can be greatly accelerated in the presence of catalytic TMSOTf or TfOH, we report herein a new discovery that glycosyl chlorides are even more effective glycosyl do
Glycosylation with Disarmed Glycosyl Bromides Promoted by Iodonium Ions

Iodonium ions have been developed for activating glycosyl bromides in the coupling to glycosyl acceptors. The iodonium ions are generated from N-iodosuccinimide and a protic acid such as camphorsulfonic acid or triflic acid, where the latter gives the most reactive promoter system. The couplings occur with the release of iodine monobromide, and the best results are obtained with benzoylated glycosyl donors and acceptors. In this way, disarmed glycosyl bromides can serve as glycosyl donors without the use of heavy-metal salts.

A very elegant Fraser-Reid armed-disarmed approach recently expanded to the building blocks of the superarmed and superdisarmed series shows very high utility in chemoselective oligosaccharide synthesis. Although a number of studies dedicated to the chemo
