TCI Practical Example: One-Pot Palladium-Catalyzed Fluorosulfonylation of an Aryl Bromide Using DABSO and NFSI

Used Chemicals
-
Procedure
-
To a solution of 4-bromobiphenyl (1.17 g, 5.00 mmol), DABSO (721 mg, 3.00 mmol), and PdCl2(Amphos)2 (177 mg, 0.25 mmol) in anhydrous isopropyl alcohol (20 mL) was added triethylamine (2.1 mL, 15 mmol) at room temperature and the mixture was stirred at 75 °C for 23 hours. The suspension was cooled at room temperature and NFSI (2.36 g, 7.5 mmol) was added and the reaction mixture stirred for 3 hours until completion. The solvent was removed under reduced pressure. The residue was diluted with ethyl acetate (20 mL) and filtrated through celite pad. The filtrate was washed with saturated aqueous Na2S2O3 solution (20 mL) and brine (20 mL), dried over sodium sulfate and filtered. The solvent was removed under reduced pressure and the residue was purified by medium pressure preparative chromatography (ethyl acetate:hexane = 2:98 - 5:95 on silica gel) to give compound 1 as a white solid (928 mg, 79%).

Application
An Enantioselective Fluorination of α-Branched Aldehydes Using Newly Developed Chiral Amine Catalyst
Typical Procedure (synthesis of 2-fluoro alcohol; Ar=Ph, R1=CH3):
To a solution of the chiral amine catalyst [E1267] (20 mg, 0.026 mmol, 10 mol%) in toluene (0.54 mL) is added 3,5-dinitrobenzoic acid (5.5 mg, 0.026 mmol, 10 mol%), 2-phenylpropionaldehyde (52 mg, 0.39 mmol, 1.5 eq.), and N-fluorobenzenesulfonimide (NFSI) (0.26 mmol, 82 mg, 1 eq.) at 0 °C. The reaction mixture is stirred at 0 °C for 48 h, then poured into CH3OH/CH2Cl2 (1:4, 1.3 mL) at 0 °C. To this solution, NaBH4 (1.6 mmol, 6 eq.) is added, and the mixture is stirred at room temperature for 1 h. The reaction is quenched with saturated aq.NH4Cl, and the mixture is extracted with Et2O. The organic layer is dried over Na2SO4, and concentrated. The residue is purified by silica gel chromatography (eluent: hexane/ethyl acetate = 3/1) to give (S)-2-fluoro-2-phenylpropan-1-ol (34.5 mg, 86% yield based on NFSI, 95% ee) as a white solid.

Application
Copper-catalyzed Direct Amidation of Heterocycles with N-Fluorobenzenesulfonimide
Typical Procedure:
In a dry 25 mL round-bottom flask, thiophene (0.5 mmol, 1 eq.), NFSI (0.6 mmol, 1.2 eq.) and CuI (5 mol%) are dissolved in DCE (3 mL), the resulting mixture is put into a preheated oil bath (60 °C) for 8 h. The solution is then cooled to room temperature, evaporated under reduced pressure, diluted with ethyl acetate, washed with a saturated aqueous solution of NaCl, dried over Na2SO4, filtered and evaporated under reduced pressure. The crude product is purified by silica gel column chromatography to afford the corresponding product (166.7 mg, Y. 88 %).
