aReaction conditions: 1 (0.05 mmol), BG5 (8 mol%), Ag2MoO4 (4 mol%), KHSO4(0.3 equiv.) and 25% aqueous H2O2 (1.2 equiv.) in 1.0 mL iPr2O at 0 °C for 36-48 h, The isolated yields were given, The er values were determined by HPLC analysis on a chiral stationary phase. bBG5 (2 mol%) and Ag2MoO4 (2 mol%) were used.
