                                    A series of 1,2,3-triazole derivatives was synthesized from N-phthalimidoalkyl-azides (A(1)-A(4)) and alkynes (a-e) under ultrasound irradiation in the presence of CuI, Et3N and DMF as solvent. The present protocol afforded 18 new 1,2,3-triazoles (1-4) in good-to-excellent yields (67-98%).
