実験手順

In 10 ml of methanol was dissolved 830 mg of 1-(3,4-diacetoxyphenyl)-1-nonen-3-one and after adding 7.5 ml of an aqueous 1N-sodium hydroxide solution to the solution, the mixture was stirred for 30 minutes at room temperature. Then, the reaction mixture was ice-cooled and after adding thereto 25 ml of water, the mixture was acidified with the addition of 5 ml of an aqueous 1N-hydrochloric acid solution to form crystals, which were collected by filtration and washed with water to provide 580 mg of 1-(3,4-dihydroxyphenyl)-1-nonen-3-one.
