Galactoside soybean isoflavone and synthetic method thereof

摘要: The invention discloses galactoside soybean isoflavone and a synthetic method thereof. comprises the following steps: (1), D-galactose is added to three-mouth flask, acetic anhydride under stirring, then 100 ml of an organic solvent I added, yellow viscous solid intermediate obtained; (2), are 200 II ice bath adopted for cooling, boron trifluoride etherate solution dropwise white (3), III sodium methoxide slowly, large quantity solids separated out subjected suction filtration, filter cake washed with vacuum drying, target compound, namely, obtained. have beneficial effects that process flow short, conversion cost low, bioavailability improved obviously as compared conventional method, good medicinal prospect.
