    • 2 (6 mL) at -40°C was added dropwise under argon a solution of DMDO (Adam, W.; Bialas, J.; Hadjiarapoglou, L. Chem. Ber. 1991, 124, 2377-2377) (12 mL). The resultant mixture was stirred at -40°C for 7 h 30 min and evaporated under reduced pressure without warming. The residue was purified by chromatography on silica gel (EtOAc/cyclohexane, 2:8) to give 113 mg (38%) of 17 as a colourless oil
