5-Thioglucosylation of a 1,6-anhydro-2-azido-2-deoxy-β-d-glucopyranose derivative was carried out with various 1,5-dithioglucosyl donors. The use of per-O-acetyl donors resulted in poor yields of an α-disaccharide. On the other hand, per-O-benzyl donors s

The 5,6-O-thiocarbonyl-α-D-glucofuranose derivatives 2, when subjected to one of the following reactions, undergo a radical-promoted thione-thiol rearrangement to yield the 5-S-thiolcarbonates of gluco-configuration 8 as the major product. The reactions are, (A) thermolysis with a catalytic amount of tributyltin hydride and AIBN, (B) photolysis with hexabutyldistannane, and (C) thermolysis with dimethyl phosphonate and benzoyl peroxide. On the other hand, thermolysis of 2 with trialkylsilane (condition D) yielded olefins 13 as the major product. The 5-S-gluco product 8 was converted, in three steps, to 5-thioglucose (21) in 55% yield.

5-Thio-D-glucose was transformed into 1,5-dithio analog 5 through a sequence involving anomeric bromination followed by a Cerny hydrosulfurization reaction.The nucleophilic reactivity of this first representative of a new class of sugar mercaptans was inv
