Reference of 2425-28-7, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.2425-28-7, name is 2-Bromo-1-phenylethan-1-ol, molecular formula is C8H9BrO, molecular weight is 201.0605, as common compound, the synthetic route is as follows.

General procedure: A round-bottom flask was charged with alcohol (2 mmol), CuOTf (0.1 mmol, 0.05 equiv) (S)-5-(pyrrolidin-2-yl)-1H-tetrazole (0.1 mmol, 0.05 equiv), TEMPO (0.1 mmol, 0.05 equiv), t-BuOK (2 mmol, 1 equiv) and DMF (5 ml). The reaction mixture was stirred at 25 C open to air until the completion of the reaction, as monitored by TLC. The mixture was then diluted with CH2Cl2 (20 ml), washed with water, dried over Na2SO4, and evaporated under vacuum to give the crude product, which was purified by column chromatography to give the pure product.

General procedure: To a solution of the olefin (0.5-1.2mmol) in 10-16mL of acetonitrile-water (1:1) mixture was added NBS (1.05equiv) at rt. The reaction mixture was stirred until all the olefin was consumed, as monitored by TLC analysis. Subsequently, TetMe-IA (10mol%) and Oxone (1.0equiv) were introduced into the reaction mixture, and the stirring was continued. After completion of the oxidation as judged by TLC analysis, the reaction mixture was washed with saturated NaHCO3 solution. The organic matter was extracted 2-3 times with ethyl acetate or dichloromethane, and the combined organic extract was dried over anhyd Na2SO4. The solvent was removed in vacuo and the resultant residue was subjected to a short-pad silica gel column chromatography to isolate pure alpha-bromoketone.
