Reaction Steps

To a suspension formed from metallic tin (730 mg, 6.15 mmoles), diethyl ether (12.5 ml) and water (3.1 ml) were added 1.10 g (6.15 mmoles) of methyl 2-bromomethyl-2-propenoate and 1.11 g (6.77 mmoles) of 3-(4-methoxyphenyl) propanal, with catalytic quantities of acetic acid. The mixture was kept warm at 50° C. with stirring for 9 hours. At the end of this time it was poured into water (200 ml) and an extraction was performed with diethyl ether (3×100 ml). The result was dried over anhydrous sodium sulphate and vacuum concentrated, giving an oil 780 mg (70% yield) of 5-[2-(4-methoxyphenyl)-ethyl]-3-metylene-dihydrofuran-2-one [(I), R═CH3; R1═H].
