The Cycloaddition Way to Glycosyl Transfer

Abstract

“…invent truly new and different glycosylation strategies that will not require a bimolecular reaction to occur between a developing oxocarbonium ion and a sterically hindered lowly nucleophilic alchol…” This challenge by F. Barresi and O. Hindsgaul to all carbohydrate chemists now has a novel reply, which can be described by the sequence in Equation (a).
