Typical Procedure1b) :
A solution of 2a (R=H) (216 mg, 1.0 mmol), 1 (92.2 mg, 0.15 mmol, 15 mol%) and mCPBA (269 mg, 1.2 mmol, 1.2 eq.) in CHCl3 (50 mL) is stirred at 0 °C. After 18 h, the resulting mixture is poured into aqueous Na2S2O3 (20 mL) and aqueous NaHCO3, and extracted with CHCl3 (2 times). The organic layers are dried over anhydrous MgSO4 and solvents are removed in vacuo. The residue is purified by flash column chromatography on silica gel (hexane-EtOAc = 10:1 to 4:1) to give 3a (129 mg, 0.6 mmol) in 60% yield (92%ee).
