Application
BF3·Et2O Functioning as a Fluorine Source in an PhIO mediated Intermolecular Aminofluorination

B0527

Typical Procedure: To a solution of N-(but-3-en-1-yl)-4-methylbenzenesulfonamide (45 mg, 0.2 mmol) in CH2Cl2 (6 mL) in a flask are added BF3·Et2O (28.2 mg, 0.2 mmol) and PhIO (88 mg, 0.4 mmol). The reaction is stirred at room temperature for 4 h. The resulting mixture is diluted with ethyl acetate (50 mL). Then, the mixture is washed with sat. aqueous NaHCO3 (5 mL) and Na2S2O3 (5 mL). The separated aqueous phase is extracted with EtOAc (2×10 mL). The combined organic layer is washed with brine (10 mL), dried over MgSO4 and concentrated in vacuo to afford the crude product which is purified by flash column chromatography (Rf = 0.12, petroleum ether/EtOAc = 9/1) to give 3-fluoro-1-tosylpyrrolidine as a colorless solid (39 mg, 80% yield).

Application
Stereoselective ring-opening hydrofluorination of aryl epoxides

Typical procedure: (RS,RS)-2-Methyl-3-phenyloxirane (4.5 g), BF3· OEt2 (1.38 mL) and CH2Cl2 (134 mL) were reacted at 20 °C for 5 min. Saturated aqueous NaHCO3 was then added and the mixture was stirred vigorously until both layers became clear. The layers were separated and the organic phase was washed with sat. aq. NaHCO3. The combined aqueous phases were extracted twice with CH2Cl2 and the combined organic extracts were dried and concentrated in vacuo. The residue was purified by flash column chromatography (gradient elution, 5 % to 40 % EtOAc in 30~40 °C petrol) gave (RS,RS)-1-fluoro-1-phenylpropane-2-ol as a colorless oil (4.31 g, 83 %, more than 99:1 dr).
