A Typical Experimental Procedure for the Preparation of 5a To a mixture of ethyl 4,4,4-trifluoro-3-oxobutanoate (184.0 mg, 1.0 mmol) and 2-benzylidene-indane-1,3-dione (468.0 mg, 2.0 mmol) in MeCN (3.0 mL) was added a catalytic amount of pipreridine (8.5 mg, 0.1 mmol). The resulting mixture was stirred at r.t. until the reaction was completed (8 h, monitored by TLC). The solvent was removed under reduced pressure. And then the residue was purified by column chromatography on silica gel using PE-EtOAc [6:1 (v/v)] as eluent to afford 5a as a colorless solid in 78% yield.
