摘要

1, 3-Dipolar cycloaddition of organic azides 1, 2, or 3 to acetylenic amides 4 or 5 under solvent-free microwave irradiation produced the corresponding N-substituted C-carbamoyl- 1, 2, 3-triazoles 7a-12a in good to excellent yields. Under similar reaction conditions, 1, 3- dipolar cycloaddition of diazide 6 and acetylenic amide 4 gave the azido-triazole 13a.
