摘要
A synthetic method to triazole-fused sugars by treatment of nitroalkene-containing C-glycosides with sodium azide is described. Initial experiments conducted at room temperature gave only the 1,3-dipolar cycloaddition products. However, at elevated reaction temperature the tandem beta-elimination/cycloaddition/Michael addition yielded 1,5-disubstituted triazole-fused sugars. (C) 2009 Published by Elsevier Ltd.
