Reaction Steps

Moreover, 10 g (36 mmol) of the resulting (E)-1-(4′-hydroxy-3′-methoxyphenyl)dec-1-en-3-one was dissolved in 100 mL of ethanol followed by the addition of 1 g of palladium carbon (5% palladium) to this solution and stirring overnight at normal temperature in a hydrogen atmosphere (normal pressure). After filtering the insoluble matter, the filtrate was concentrated under reduced pressure to obtain 9.8 g of crude product. This crude product was purified by column chromatography (SiO2/CHCl3) to obtain 1-(4′-hydroxy-3′-methoxyphenyl)-3-decanone (5.6 g, yield: 58%).
