Application
Synthesis of Trifluoromethylketones from Weinreb Amides
Typical Procedure:
To a 50 mL round bottom flask equipped with a stir bar is added CsF (0.1512 g, 1.0 mmol, 0.2 eq.). Toluene (2.5 mL) is added to the flask, followed by 4-(tert-butyl)-N-methoxy-N-methylbenzamide (1.11 g, 5.0 mmol, 1 eq.). The flask is sealed with a septum equipped with an inlet needle as an exit valve. The flask is cooled to 0 °C for 10 minutes. Once cooled, TMSCF3 (1.42 g, 10.0 mmol, 2 eq.) is added to the reaction mixture dropwise over a period of ≈ 10 minutes. After completion of addition, the reaction mixture is allowed to stir at 0 °C for 10 minutes. The cooling bath is removed and the reaction mixture is allowed to stir at room temperature overnight. (Upon reaching room temperature, the reaction occurs and is mildly exothermic and gas is evolved.) Reaction progress is monitored by 1H NMR.
Once complete conversion to the silylated intermediate is confirmed, water (5 mL) followed by TBAF (5 mL, 1 M in THF, 1 eq.) is added to the reaction flask. The flask is equipped with a reflux condenser, open to air. The contents are then heated to 50 °C, and allowed to stir at that temperature for 2 hours. Once cooled to room temperature, the reaction mixture is diluted with Et2O (≈ 30 mL), and transferred to a separatory funnel. The organic layer is washed with deionized water (3 × 30 mL), followed with a brine solution (1 × 30 mL). The organic layer is dried with Na2SO4 and the solvent is removed in vacuo by rotary evaporation to yield crude trifluoromethylketone. Further purification is accomplished by flash chromatography (hexane : EtOAc = 8 : 2) to produce the pure CF3 ketone as an orange solid (0.935 g, Y. 81%).
