反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2-bromophenol (6.12 g, 35.3 mmol) and propargyl bromide (5.67 g, 38.1 mmol) were dissolved in DMF (34 ml). This solution was added with potassium carbonate (10.9 g, 78.9 mmol) and stirred at room temperature for 14 hours. The reaction solution was added with ethyl acetate, sequentially washed with water and saturated sodium chloride water, and dried with anhydrous sodium sulfate. Concentration under reduced pressure was carried out to obtain the title compound (7.91 g, 98.0%) as a yellow oily product. sequentially washed with water and saturated sodium chloride water dried with anhydrous sodium sulfate Concentration under reduced pressure

实验步骤: To a stirred solution of 2-bromophenol (50.0 g, 289 mmol) and progargyl bromide (41.3 g, 347 mmol) in dry ACN (500 mL) was added K2CO3 (47.9 g, 347 mmol) and the solution was stirred overnight at rt. The solvent was removed and the residue was poured into water and extracted with Et2O. The combined organic layers were dried over Na2SO4, filtered and concentrated to give compound P34a (60 g, 98%) as an oil.
