An efficient synthesis of novel bis-triazole glycoconjugates via a three-component condensation as a key reaction

•Novel bis-triazole linked glycoconjugates were designed and synthesized.•Utilizing a three-component condensation as a key step to reduce reaction steps.•Structure/reactivity study of intermediate N2-hydroxymethyl triazole was emphasized.•The novel glycoconjugates would be provided with potential antivirus activity.

Novel bis-triazole glycoconjugates were designed and prepared successfully via 5 steps from propargyl per-O-acetyl-β-d-glucoside or xyloside (total yield of 48–53%), after utilizing a three-component condensation of propargyl per-O-acetyl-β-d-glycoside, formaldehyde, and sodium azide as a key step to synthesize 2-hydroxymethyl-2H-1,2,3-triazole glycoconjugates. The developed bis-triazole glycoconjugates would be crucial in antivirus pharmacology and chemical biology.
