95% With copper(l) iodide; L-proline; sodium hydroxide; In dimethyl sulfoxide; at 80℃; for 12h;Inert atmosphere; Sealed tube; General procedure: A sealable reaction tube equipped with a magnetic stirrer bar was charged with 2-iodophenols 1 (1 mmol), alkynes 2 (1 mmol), NaOH (2 mmol), CuI (0.1 mmol), proline (0.3 mmol) and DMSO (5 mL), and the reaction vessel placed in an oil bath at 80 C under N2 . After stirring the mixture at this temperature for 12 h, it was cooled to room temperature and diluted with ethyl acetate, washed with water and brine, dried over by MgSO4. After the solvent was removed under reduced pressure, the residue was purified by column chromatography on silica gel to afford the corresponding product.

The reactionwas monitored by TLC and GC.The mixture was cooled down toroom temperature after full conversion, then diluted with dichloromethaneand washed with water three times. The organic layerwas separated and washed with brine followed by drying with anhydrousNa2SO4. The filtrate was concentrated in vacuo to afford thecrude product, which was purified by flash column chromatography onsilica gel (petroleum ether).

A palladium complex(2a or 2b, 0.0005 mmol) was added to the mixture, followed byDMSO (ca. 2 mL) as a solvent, and then the reaction mixture washeated (either at 90C or at 120C) for 10 h. The reaction mixturewas cooled to room temperature, and water (ca. 20 mL) was added.The resulting mixture was extracted with EtOAc (ca. 50 mL). Theorganic layer was further extracted with EtOAc (ca. 2 20 mL). Theorganic layers were combined and vacuum dried to obtain a crudeproduct that was subsequently puried by column chromatog-raphy.
