Sulfoxide-mediated intramolecular aglycone

Sulfoxide-mediated intramolecular aglycone delivery has been conducted with a temporary linker formed in situ by the reaction of lanthanide triflates with the donor and acceptor-based alcohols (Scheme 4.66) [336], However, as the selectivities recorded were modest, it has to be assumed that intermolecular glycosylation was an important side reaction in this chemistry.
