Carbohydrates are an important class of natural compounds, which are involved in immunology, gene expression, as a fuel source for metabolism, etc. It is therefore of interest to be able to control the outcome of chemical glycosylations, with regards to stereoselectivity and high yield. Different procedures for doing so have been established relying on either a catalyst or a promoter. However, the procedures often involve temperatures below 0 • C and/or harsh reagents, making them inconvenient for non-specialists. It is intrinsically challenging to control the stereoselectivity at the anomeric position, due to the complicated nature of carbohydrates and glycosylation reactions.
