Then 1.65 g (14.7 mmol) of t-BuOK in 18 mL of t-BuOH was added over a period of 4 min. The resultant tannish orange mixture was stirred at ambient temperature for 21 h and then diluted with 200 mL of hexane and 100 mL of H2 O containing 2 drops of HOAc. The aqueous layer was extracted with 100 mL of hexane. The organic extracts were washed with two 50-mL portions of H2 O and brine, dried (MgSO4), and concentrated at reduced pressure to a yellow oil and solid which--after extraction with 100-mL portions of hexane and 5% EtOAc/hexane--gave 5.7 g of yellow oil and some solid. This material was chromatographed on 300 g of silica gel. Elution with 600 mL of hexane followed by 5% EtOAc/hexane gave two fractions of 1.7 g and 1.4 g. The first fraction was rechromatographed on 100 g of silica gel eluted in the same manner to afford 0.7 g of yellow oil, which was combined with the second fraction. These combined fractions were purified by preparative LC with 3% EtOAc/hexane to give 1.89 g (42%) of viscous yellow oil, which solidified on cooling, mp 35°-37° C. |
