Embodiment 2
[0032] Mode( I ) in trifluoromethylated parthenolide derivatives I-3 preparation of
[0033]
[0034] compound 6 The synthesis of: under the protection of argon, the compound 5 (12.34 g, 62.93 mmol) was dissolved in dry tetrahydrofuran (125 mL), and NaHMDS (2 M in THF, 63.0 mL, 126.0 mmol) was added in an ice-water bath. After stirring for half an hour, dry tetrahydrofuran (250 mL) was added . Then the compound 4 (14.23 g, 75.53 mmol) was slowly added dropwise. Stirred under ice-water bath for 4 h, with KHSO 4 The solution (0.5 M) was quenched, and the pH of the solution was adjusted to 4, extracted, concentrated under reduced pressure, and silica gel column chromatography (petroleum ether: ethyl acetate = 20:1-8:1) to obtain the compound 6 (11.67 g, 80%).
