Reaction Steps

The crude oxirane 19 from above (2.4 g, 7.84 mmol) is dissolved in 50 ml of THF and cooled to −78° C. in a dry-ice bath. At this temperature, n-BuLi (1.6M in hexane, 4.9 ml, 7.84 mmol) is added drop wise. The mixture is then stirred for one hour and allowed to warm up to 0° C. After careful hydrolysis and extraction with EtOAc the crude is purified by Flash-chromatography (ethyl acetate/hexanes (from 5:95 to 25:75), silicagel).
