Abstract

The invention discloses alizarin aminophosphonate derivatives and their synthesis method and use. The synthesis method comprises that alizarin and 2-bromopropionic acid as raw materials are dissolved in a polar solvent, the solution undergoes a reaction in the presence of potassium hydroxide as an acid binding agent to produce 2-(1-hydroxy-9, 10-dioxo-9,10-dihydroanthracene-2-yloxy)propionic acid, the 2-(1-hydroxy-9,10-dioxo-9,10-dihydroanthracene-2-yloxy)propionic acid and alpha-aminophosphonate as raw materials are dissolved in a polar solvent, the solution undergoes a full reaction in the presence of 1-hydroxybenzotriazole as a catalyst and 1-(3-dimethylaminopropyl)-3-ethyl-carbodiimide hydrochloride as a condensing agent, trichloromethane is added into the reaction produce solution, a water washing process is carried out, and an organic layer is collected and then is subjected to chromatography purification by a silicagel column. The alizarin aminophosphonate derivatives have a general structural formula (I).

Description

technical field [0001] The invention relates to alizarin derivatives, in particular to alizarin aminophosphonate derivatives and their synthesis method and application. Background technique [0002] Alizarin (Alizarin, chemical name is 1,2-dihydroxy 9,10-anthraquinone), since alizarin was extracted and purified from the root of madder, alizarin and its derivatives have been used in total synthesis, structural modification, and biological activity. research has aroused widespread concern. Existing studies have shown that alizarin has specific hypoglycemic, anti-inflammatory, antibacterial, and antiviral effects, and it has also been reported that alizarin has certain antitumor activity. [0003] α-Aminophosphonate is an intermediate compound with biological activity and pharmaceutical activity, and has been widely used in antibiotics, fungicides, enzyme inhibitors and herbicides. However, there are no public reports on the introduction of α-aminophosphonate functional group...
