Alpha-D-Glucose → D-Glucosone

참여 물질

반응 단계

To a solution of α-D-glucose (4.5 g) in water (10 ml), a solution of cupric acetate (20 g) in methanol (250 ml) was added, and the resultant mixture was heated on a water bath for 1 hour. The reaction mixture was cooled, and the precipitated cuprous oxide was eliminated by filtration. Hydrogen sulfide gas was introduced into the filtrate for about 1 minute to precipitate the unreacted cupric acetate in the form of cupric sulfide. After elimination of the precipitate by filtration, the filtrate was treated with a small amount of activated charcoal and concentrated under reduced pressure to give glucosone in a syrupy state.
