A mild, general method for the stereoselective synthesis of ∝-2-deoxy disaccharides is described using 2-deoxy-2-pyridyl 1-thioglycosides 4, 7, 8 as glycosyl donors and methyl iodide as an activator. Thus, a disaccharide 6 component of avermectin family is synthesized starting from D-glucose.

The title synthesis is described by 1,2-addition of 20mercaptpyridine (1) on simple (2 and 3) as well as on sensitive glycal saccharides (7 and 8) to obtain the respective 2-deoxy 2-pyridyl 1-thioglycopyranosyl donors (4, 5, 9, 10). Glycosylations by the proven methyl iodide activation procedure is described.
