SYNTHESIS OF β-GLYCOSIDES OF N-ACETYLGLUCOSAMINE IN THE PRESENCE OF Hgl_2

摘要

The use of HgBr2 as catalyst for glycosylation reactions in the series both of neutral sugars [1] and of aminosugars is known: In the second case, either azidosugars or phthalimide derivatives of aminosugars are usually used as glycosyl donors. At the same time, Hgl2 has been used only for the rra/w-glycosylation of D-mannose derivatives [3].
