Procedure: Ethyl 3-(4-benzyloxyphenyl)but-2-enoate (3.4 g) in ethyl acetate (100 ml) was hydrogenated over a 10% palladium-on-carbon catalyst (250 mg) at atmospheric pressure/ambient temperature. The catalyst was removed by filtration and the filtrate evaporated to give an oil. The oil was purified by chromatography on silica gel using a 4/1 (v/v) mixture of hexane and ethyl acetate as eluent to give ethyl 3-(4-hydroxyphenyl)butanoate (1.51 g) as a pale yellow oil; NMR(CDCl3): 1.20(3H,t), 1.27(3H,d), 2.52(2H,q), 3.22(1H,m), 4.08(2H,q), 4.84(1H,s), 6.71(2H,m) and 7.08(2H,m); m/z 208(M). Ethyl 3-(4-allyloxyphenyl)butanoate was prepared using the procedue used to prepare ethyl 3-(4-allyloxyphenyl)propionate (see Example 1) but using ethyl 3-(4-hydroxyphenyl)butanoate in place of ethyl 3-(4-hydroxyphenyl)propionate; NMR(CDCl3) 1.17(3H,t), 1.25(3H,d), 2.51(2H,m), 3.22(1H,m), 4.05(2H,q), 4.50(2H,m), 5.33(2H,m), 6.06(1H,m), 6.82(2H,m) and 7.11(2H,m); m/z 249 (M+H).

Procedure: To a stirred solution of 38.1 (5.00 g, 17.1 mmol) in EtOH (100 mL) at room temperature was added PPTS. The resulting solution was stirred for 16 hours and then concentrated in vacuo. The residue was purified by flash chromatography (SiO2 gel 60, eluted with 0%-20% EtOAc in hexanes). Fractions containing the desired product were combined and concentrated to give 38.2 (3.00 g, 84%) as a colorless oil. MS ESI (pos.) m/e: 226.1 (M+H2O)+. concentrated in vacuo The residue was purified by flash chromatography (SiO2 gel 60, eluted with 0%-20% EtOAc in hexanes) Fractions containing the desired product concentrated
