General procedure: To a stirred solution of imidazolium salts (0.045 mmol), NaOtBu (4.3 mg, 0.045 mmol) and CuCl (4.5mg, 0.045 mmol) was added THF (0.5 mL, 0.09 M) at 30 oC under argon atmosphere. After stirring for 2 h, the solution of K+[CF3B(OMe)3]- (63.5 mg, 0.3 mmol, 6.0 equiv) in DMF (0.5 mL) was added dropwise. Then the mixture was kept stirring at 30 oC for 10 h. After that, the reaction was quenched with water. Aqueous layer was extracted with EtOAc (15 mL x 3), and the combined organic layers was washed with brine, dried over Na2SO4 and concentrated under reduced pressure. Then the crude product was purified by column chromatography on silica gel to give the imidazolinone 3b-d.
