Direct α-Oxyacylation of Carbonyl Compounds
Typical Procedure: α-Oxyacylation of Ketones
To a stirring mixture of ketone (1 mmol), carboxylic acid (1 mmol) and Bu4NI (36.9 mg, 0.1 mmol, 10 mol%) in AcOEt (5 mL) is added tert-butyl hydroperoxide (5.5 M in nonane or decane, 364 µL, 2 mmol) at room temperature. The resulting mixture is heated to 75 °C. The reaction is monitored by TLC analysis. After the reaction is completed, the reaction mixture is cooled to room temperature and poured into sat. Na2S2O3 aq. (5 mL) and sat. NaHCO3 aq. (5 mL) extracted with AcOEt (twice), and washed with brine. The combined organic layers are dried over anhydrous Na2SO4 and solvents are removed in vacuo. The residue is purified by flash column chromatography on silica gel (hexane–AcOEt as eluent) to give the corresponding analytically pure product.
