On the use of the haloetherification method to synthesize fully functionalized disaccharides

Article abstract of DOI:10.1016/S0040-4020(01)97587-8

Synthetic routes to the fully functionalized α-linked disaccharides 19 21 and 25 are described starting from a common intermediate the iodo acetate 15. This substance was in turn prepared via a haloetherification reaction between the allal derivative 13 the galactose alcohol 14 and an "iodonium" equivalent.
