참여 물질

반응 조건

반응 단계

1.0 g (5.94 mmol) of 4,4,4-trifluoro-2-butenoic acid ethyl ester and 0.15 mL (1.19 mmol) of 1,1,3,3-tetramethyl guanidine and 1.6 mL (29.8 mmol) of nitromethane were mixed. The resulting mixture was cooled to 0° C. and then stirred for 3 hours at room temperature, followed by addition of 100 mL of ethylacetoacetate. The reaction mixture was washed with water, and then an organic layer was dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to give 1.1 g (4.80 mmol) of the title compound in a yield of 81%.
