反応手順

To a solution of 4-iodobenzaldehyde (0.116 g, 0.5 mmol), acrolein diethylacetal (0.3 mL, 1.5 mmol), tetra-n-butylammonium chloride (0.139 g, 0.5 mmol) and triethylamine in anhydrous dimethylformamide (2 mL), palladium acetate (0.003 g, 0.015 mmol) was added. The reaction mixture was heated at 90° C. and stirred for 16 h. The reaction mixture was diluted with 2 N hydrochloric acid and extracted with diethyl ether. The solvent was evaporated in vacuo to leave a residue which was purified by column chromatography (silica gel) employing 1-5% ethyl acetate in hexane as eluents to obtain 3-(4-formyl-phenyl)-propionic acid ethyl ester (0.734 g).
