Method for preparing acetyl rhamnose invented by Chengdu Institute of Biology

March 06, 2024

In the synthesis of natural products and active polysaccharides, 3,4-di-O-acetyl-L-rhamnose is an important raw material. Current synthesis methods have the disadvantages of expensive raw materials, cumbersome operations, and the need for separation and purification of intermediate products.

On March 8th, I learned from the Science and Technology Department of Chengdu Institute of Biology Licensing. The invention first reacts L-rhamnose with acetic acid and acetic anhydride under the catalytic action of p-toluenesulfonic acid (perchloric acid, sulfamic acid, zinc chloride and sulfuric acid) to produce 1,2,3,4- Tetra-O-acetyl-L-rhamnose, then add acetyl bromide and methanol to produce 1-bromo-2,3,4-tri-O-acetyl-L-rhamnose, then add ethyl acetate (Acetone), sodium dihydrogen phosphate aqueous solution (phosphate buffer solution, potassium dihydrogen phosphate solution) and zinc powder, react to produce 3,4-di-O-acetyl-L-rhamnorenose.

The method of the invention is simple in operation, short in technological process, high in yield, short in reaction time, low in cost, low in waste, low in environmental pollution, and easy to industrialize.
