Example Embodiment
[0028] Example 1
[0029] 4-(3-(Hydroxyamino)-3-oxopropyl-1-en-1-yl)phenylbutane-1-sulfonate
[0030]
[0031] It is called spartamin G1.
[0032] Dissolve p-coumaric acid (1 mmol) in a mixed solution of 10 mL of dichloromethane and 1 mL of N,N-dimethylformamide, add n-butylsulfonyl chloride, stir under ice bath conditions for 30-60 min, add dicyclohexyl Carbodiimide (1.5 mmol) and 4-dimethylaminopyridine (0.5 mmol) were moved to room temperature and stirred for 4-12 h, followed by thin layer chromatography. After the reaction, the precipitate was filtered, and the filtrate was extracted with ethyl acetate , washed with saturated sodium chloride solution, distilled off the organic solvent under reduced pressure, recrystallized with a mixed solvent of N,N-dimethylformamide and ethanol, and the obtained compound was dissolved in a mixed solution of 10 mL of isopropanol and 1 mL of piperidine, Hydroxylamine hydrochloride (1 mmol) was added, stirred for 4-8 h under ice bath c...
