88% | With silver trifluoromethanesulfonate; In 1,2-dichloro-ethane; at 50 - 60℃;Inert atmosphere; | General procedure: Silver triflate (0.02 mmol, 10 mol %) was added to a solution of 2-alkynylbenzaldehyde 1 (0.2 mmol), sulfonohydrazide (0.2 mmol), and carbodiimide compound 2 (0.4 mmol, 2.0 equiv) in DCE (2.0 mL). The solution was stirred at 50-60 C for overnight. After completion of reaction as indicated by TLC, the reaction was quenched by addition of saturated aqueous NH4Cl (5.0 mL), and the mixture was extracted with EtOAc (4.0 mL×3). The combined organic layer was dried over Na2SO4, and concentrated in vacuo. The residue was purified by column chromatography on silica gel to provide the desired product 3. |
