Synthesis and glycogen phosphorylase inhibitory activity of N-(β-d-glucopyranosyl)amides possessing 1,4-benzodioxane moiety

A series of N-(β-d-glucopyranosyl)amides 5d–i were synthesized by PMe3 mediated Staudinger reaction of O-peracetylated β-d-glucopyranosyl azide (1) followed by acylation with carboxylic acids 3d–i and subsequent Zemplén deacetylation. The new compounds were tested for their inhibitory activity against rabbit muscle glycogen phosphorylase and the structure–activity relationships of these compounds are also discussed in this paper.
