---|---|---|
63.6 mg | Stage #1: With 2,2,2-Trifluoroacetophenone; dihydrogen peroxide In acetonitrile; <i>tert</i>-butyl alcohol at 20℃; for 18 h; Green chemistry Stage #2: With 1,8-diazabicyclo[5.4.0]undec-7-ene In dichloromethane at 60℃; for 1 h; Green chemistry |
General procedure: The respective o-allylphenol 2 (0.40 mmol) was placed in a roundbottomed flask followed by consecutive addition of t-BuOH (0.4 mL), 2,2,2-trifluoro-1-phenylethanone (7.0 mg, 0.08 mmol), aqueous buffer solution (0.4 mL, 0.6 M K2CO3/4 × 10–4 M EDTA disodium salt), MeCN (0.64 mL, 6.40 mmol), and 30percent aq H2O2 (1.38 mL, 6.40 mmol).The reaction mixture was left stirring for 18 h. The crude product was dried (Na2SO4) and the solvent was removed in vacuo. The mixture was dissolved in CH2Cl2 (1.00 mL) followed by addition of DBU (54.0mg, 0.40 mmol). The mixture was stirred for 1 h at 60 °C and then purified by flash column chromatography (40–60percent EtOAc in PE) to afford the desired product 3. |
