Versuchsvorschrift
To a solution of (1R,2R)-2-benzoyloxy-1,2-epoxycyclohexane (0.030 g, 0.137 mmol, 93% ee) in anhydrous CH2Cl2 (0.4 mL) was added YbCl3 (0.0038 g, 0.0137 mmol). Upon stirring at room temperature for 30 min, the reaction mixture was quenched with saturated NaHCO3 solution, extracted with ether, dried over anhydrous Na2SO4, filtered, concentrated, and purified on buffered silica gel (0.5-1% Et3N) by flash column chromatography [EtOAc-CH2Cl2-hexane (3:7:40)] to afford (S)-2-benzoyloxy cyclohexanone (0.022 g, 73% yield, 88% ee).
