[0029] The preparation method of a novel ferulic acid aromatic derivative of the present invention comprises the following steps:
[0030] Dissolve ferulic acid in a mixed solution of dichloromethane and N,N-dimethylformamide, add various arylsulfonyl chlorides, stir for 60 minutes under ice bath conditions, add dicyclohexylcarbodiimide and 4-Dimethylaminopyridine, moved to room temperature and stirred for 10 h, followed by thin-layer chromatography. After the reaction, the precipitate was filtered, and the filtrate was extracted with an extractant, washed with saturated sodium chloride solution, dried with saturated sodium sulfate, and reduced The organic solvent was removed by pressure distillation, and the mixed solvent of N,N-dimethylformamide and ethanol was used for recrystallization to obtain a new class of aromatic derivatives of ferulic acid.
[0031] The molar volume ratio of ferulic acid and dichloromethane is 1mmol:10mL; the volume ratio of dichloromethane and N,N-...
Embodiment 2
[0038] The difference between embodiment 2 and embodiment 1 is:
[0039] The preparation method of a novel ferulic acid aromatic derivative of the present invention comprises the following steps:
[0040] Dissolve ferulic acid in a mixed solution of dichloromethane and N,N-dimethylformamide, add various arylsulfonyl chlorides, stir for 30 minutes under ice bath conditions, add dicyclohexylcarbodiimide and 4-Dimethylaminopyridine, moved to room temperature and stirred for 12 hours, and followed the reaction by thin-layer chromatography. After the reaction was completed, the precipitate was filtered, and the filtrate was extracted with an extractant, washed with saturated sodium chloride solution, dried with saturated sodium sulfate, and reduced The organic solvent was removed by pressure distillation, and the mixed solvent of N,N-dimethylformamide and ethanol was used for recrystallization to obtain a new class of aromatic derivatives of ferulic acid.

Embodiment 3
[0044] The difference between embodiment 3 and embodiment 1 is:
[0045] The preparation method of a novel ferulic acid aromatic derivative of the present invention comprises the following steps:
[0046] Dissolve ferulic acid in a mixed solution of dichloromethane and N,N-dimethylformamide, add various arylsulfonyl chlorides, stir for 50 minutes under ice bath conditions, add dicyclohexylcarbodiimide and 4-Dimethylaminopyridine, moved to room temperature and stirred for 8 hours, and followed the reaction by thin-layer chromatography. After the reaction, the precipitate was filtered, and the filtrate was extracted with an extractant, washed with saturated sodium chloride solution, dried with saturated sodium sulfate, and reduced The organic solvent was removed by pressure distillation, and the mixed solvent of N,N-dimethylformamide and ethanol was used for recrystallization to obtain a new class of aromatic derivatives of ferulic acid. The extractant is ethyl acetate.
