Versuchsvorschrift

To a solution of 35 (70 mg, 0.34 mmol) in freshly distilled THF (3 mL) at 0° C. was added triphenyl phosphine (180 mg, 0.68 mmol) and 23 (90 mg, 0.34 mmol). DIAD (0.135 mL, 0.68 mmol) was added to the mixture dropwise. The reaction was warmed to room temperature and stirred for 4 h. The reaction mixture was treated with saturated aqueous NaHCO3 solution (2 mL), washed with water, followed by brine, dried over Na2SO4, and concentrated to give a crude mixture that was purified by column chromatography (30% 50% EtOAc in hexane) to give 36 as an oil.
