反応手順
To a 1000 mL round bottomed flask, 0.15 mol of 7-hydroxychromone, and then 2.50 g of 5% palladium carbon and 300 mL of ethanol were added. Subsequently, hydrogen was passed into the flask, and the reaction was carried out for 48 hours at 50° C. Palladium carbon was removed by sucking filtration, and ethanol was removed by rotary evaporation. Then 21.39 g of 7-hydroxychroman was obtained, with a yield of 92.4% and MS m/z (M)150.
