Reaction Steps

To a solution of 2 g (5.7 mmol) of 6-(3,4,5-trimethoxyphenyl)-2-keto-3-hexenal-diethylacetal in 50 ml of ethanol was added 20 mg of 10% palladium on carbon and the mixture hydrogenated at 50 psi for 8 hours. The catalyst was filtered and the ethanol evaporated to yield 1.8 g of 6-(3,4,5-trimethoxyphenyl)-2-keto-3-hexanal-diethylacetal as an oil. 1H NMR (CDCl3) δ 6.38 (s, 2 H), 4.50 (s, 1 H), 3.80 (s, 6 H), 3.76 (s, 3 H), 3.60 (q, 2 H), 3.50 (q, 2 H), 2.50 (m, 4 H), 1.60 (m, 4 H), 1.20 (t, 6 H).
