The 2-aminophosphonium iodide lactosamine glycoside (Lafont intermediate) readily obtained from lactose has been previously shown not to be amenable to derivatization for oligosaccharide synthesis, but has now been successfully converted via the salicylaldehyde imine into suitably protected lactosamine building blocks (13–16) for glycosylation. The titled strategy has enabled us to rapidly synthesize
