Embodiment 1
[0106] The preparation of embodiment 1 (E)-1-(2-hydroxyl-6-methoxyphenyl)-3-(5-hydroxymethylfuran-2-yl) prop-2-en-1-one (1 )
[0107]
[0108] Take 500mg (3.0mmol) of 2-hydroxy-6-methoxyacetophenone and 600mg (3.6mmol) of 5-hydroxymethylfurfural and add it to 15ml ethanol, then add 30% NaOH aqueous solution, and stir the reaction at room temperature After 24-48 hours, TLC showed that the reaction was almost complete. The reaction liquid was poured into ice water, filtered, and the solid was washed with water three times. After drying, it was separated by flash column to obtain compound (1), 312 mg, with a yield of 38%.

Embodiment 2
[0110] The preparation of embodiment 2 (E)-1-(2-hydroxyl-4-methoxyphenyl)-3-phenylprop-2-en-1-one (2)
[0111]
[0112] Using 2-hydroxy-4-methoxyacetophenone and benzaldehyde as raw materials, refer to the synthesis method of compound 1.
[0113] 1 H-NMR: 3.87(3H,s,-OCH 3 ),6.49(1H,s),6.52(1H,d,J=2.4,Ar-H),7.43(3H,m,Ar-H),7.67(1H,d,J=15.3Hz,Ar-H) ,7.65(2H,m,Ar-H),7.84(1H,d,J=9.3Hz),7.90(1H,d,J=15.3Hz),13.43(1H,s,-OH).M + = 255.2.
Embodiment 3
[0114] The preparation of embodiment 3 (E)-1-(2-hydroxyl-6-methoxyphenyl)-3-(thien-2-yl) prop-2-en-1-one (3)
[0115]
[0116] Using 2-hydroxy-6-methoxyacetophenone and thiophenecarbaldehyde as raw materials, refer to the synthesis method of compound 1.
[0117] 1 H-NMR: 3.07(3H,s,-OCH 3 ),6.43(1H,dd,J 1 =1.2,J 2 =8.4,Ar-H),6.61(1H,dd,J 1 =0.9,J 2 =8.1,Ar-H),7.10(1H,m,Ar-H),7.35(2H,m,Ar-H),7.41(1H,m,Ar-H),7.71(1H,d,J=15.3 ), 7.75 (1H, d, J = 15.3), 13.18 (1H, s, -OH). m + = 261.2.
