Embodiment 1

[0030] Amphipathic aminoinulin is a compound represented by formula (1).

[0031]

[0032] In this example, the target compound was synthesized according to the above synthetic route (1).

[0033] 1) Synthesis of Compound 1: Inulin was dried overnight at 100°C under vacuum. Take 1.62g of inulin and add it to 50mL of purified nitrogen-nitrogen dimethylformamide under the protection of nitrogen, raise the temperature until the inulin is completely dissolved, and add 3.5g of N-bromosuccinyl when the temperature of the solution drops to room temperature imine (NBS); then 5.2 g of triphenylphosphine dissolved in 30 mL of nitrogen nitrogen dimethylformamide was added dropwise at room temperature; after reacting at room temperature for 30 min, the reaction temperature was raised to 70 ° C, and React for 3h; after the reaction, pour the reaction solution into 250mL acetone to precipitate out. After the precipitate was suction filtered and washed with acetone, it was directly tran...

Embodiment 2

[0040] The difference from Example 1 is:

[0041]1) Synthesis of Compound 1: Inulin was dried overnight at 100°C under vacuum. Take 1.62g of inulin and add it to 50mL of purified nitrogen-nitrogen dimethylformamide under the protection of nitrogen, then raise the temperature until the inulin is completely dissolved, and add 3.5g of N-bromosuccinyl when the temperature of the reaction solution drops to room temperature imine (NBS) to the above reaction solution. 5.2 g of triphenylphosphine dissolved in 30 mL of nitrogen nitrogen dimethylformamide was added dropwise to the above reaction solution at room temperature, and then reacted at room temperature for 30 minutes, then the temperature of the reaction system was raised to 70 ° C, and at this temperature After the reaction, the reaction solution was poured into 250 mL of acetone, and a precipitate was precipitated. After the precipitate was suction-filtered and washed with acetone, it was directly transferred to 180 mL of d...

Embodiment 3

[0045] The difference from Example 1 is:

[0046] 1) Synthesis of Compound 1: Inulin was dried overnight at 100°C under vacuum. Take 1.62g of inulin and add it to 50mL of purified nitrogen-nitrogen dimethylformamide under the protection of nitrogen, raise the temperature until the inulin is completely dissolved, and add 3.5g of N-bromosuccinyl when the temperature of the reaction solution drops to room temperature imine (NBS) to the above reaction solution. Weigh 5.2 g of triphenylphosphine and dissolve it in 30 mL of nitrogen-nitrogen dimethylformamide. This solution was added dropwise to the reaction solution at room temperature. After the reaction solution was reacted at room temperature for 30 minutes, the temperature of the reaction system was raised to 70°C. After the reaction was carried out at 70°C for 3 hours, the reaction solution was poured into 250mL acetone, and a precipitate was precipitated. After the precipitate was suction-filtered and washed with acetone, i...

Abstract

Disclosed are amphiphilic amino inulin and a preparation method therefor. The amphiphilic amino inulin is shown in formula (1), wherein R represents H, CH3, CH3CH2CH2, (CH3)2CH, or C6H5, and the average of n ranges from 10 to 35. The amphiphilic amino inulin is prepared through the following method: performing the halogenated reaction on the primary hydroxyl of the inulin; the inulin after the reaction reacting with sodium azide or lithium azide for 8-24h at 40-70°C; after purification, obtaining 6 azide-3, and 4-diacyl-6 deoxy inulin; and reducing the 6 azide-3 and the 4-diacyl-6 deoxy inulin with triphenylphosphine to obtain the amphiphilic amino inulin.

Description

technical field [0001] The invention relates to the field of daily chemicals and the pharmaceutical industry, in particular to an amphipathic aminoinulin and its preparation. Background technique [0002] Inulin, also known as inulin, is a biological polysaccharide. It is produced by connecting D-fructofuranose molecules with β-(2,1) glycosidic bonds, and the end of each inulin molecule is connected with a glucose residue with α-(1,2) glycosidic bonds. The degree of polymerization is usually 2-60, and the average The degree of polymerization is 10. [0003] Inulin widely exists in some microorganisms and fungi in nature. However, it mainly exists in plants, such as Jerusalem artichoke, chicory, salsify, dahlia tubers, etc., among which Jerusalem artichoke is the main source of raw materials for inulin production. Jerusalem artichoke is commonly known as Jerusalem artichoke and ghost ginger. It is native to North America and is a perennial herb plant. It is widely cultivat...
