Asymmetric epoxidation of -undec-2-en-l-ol

The mixture was stirred for 1 hour at — 20 °C and then anhydrous TBHP (7.5 mL, 3.2 M in Ao-octane) also added slowly via a syringe. The mixture was again stirred at —20 °C for 1 hour. (E)-IJndcc-2-cn-1 -oI (1 g, 0.0059 mol) in CH2C12 (5 mL) was added dropwise by syringe such that the temperature was maintained between —15 and — 20 °C. The reaction mixture was stirred at —20 °C for 6 hours and then placed in a freezer overnight.
