Synthesis method of isolicoflavonol

The invention provides a synthesis method of isolicoflavonol, which comprises the following steps: carrying out condensation reaction on 2,4-O-R1(protective group, the same below)-6-hydroxyacetophenone and 4-O-R2(protective group, the same below)-benzaldehyde to generate 2',4'-O-R1-6'-hydroxy-4-O-R2-chalcone; oxidizing the chalcone to generate flavonol; carrying out selective protection on 3-OH ofthe flavonol to obtain 3,5,7-O-R1-4'-O-R2-flavonol; removing the protecting group R2 from the 3,5,7-O-R1-4'-O-R2-flavonol to obtain 3,5,7-O-R1-4'-hydroxyflavonol; carrying out 1,1-dimethylpropargyl reaction on the 4,4'-OH site to obtain 3,5,7-O-R1-4'-O-(1',1''-dimethyl propargyl)flavonol; carrying out partial hydrogenation on the alkynyl of the 3,5,7-O-R1-4'-O-(1',1''-dimethyl propargyl)flavonolunder the action of a catalyst to obtain 3,5,7-O-R1-4'-O-(1',1''-dimethylpropenyl)flavonol and carrying out Claisen rearrangement on the 3,5,7-O-R1-4'-O-(1',1''-dimethylpropenyl)flavonol to obtain 3,5,7-O-R1-isolicoflavonol, and removing the protecting group R1 from the 3,5,7-O-R1-isolicoflavonol to obtain the isolicoflavonol.
