Summary: | The reaction of a mixture of 1-azide-glycopyranoside (<strong>1</strong>) and appropriate alkynes (<strong>2a-e</strong>), in the presence of CuI/Et<sub>3</sub>N as catalyst system, and acetonitrile as solvent, provided the glycoside triazoles (<strong>3a-e</strong>) in moderate-to-excellent yields (<em>60-93%)</em>. We observed that the reactivity of the alcohols decreased due to steric hindrance (prim>sec>terc). Furthermore, the use of ultrasound irradiation was favorable to furnish the desired products with excellent yields and a shorter reaction time, except for the compound (<strong>3e</strong>). <br />
