Method of constructing alpha-glucosidase inhibitor in three steps by taking imine as initial raw material
-
Paragraph 0023-0050, (2019/03/08)
The invention relates to a method of constructing an alpha-glucosidase inhibitor in three steps by taking imine as an initial raw material. By taking (E)-N-butyl-1-(4-nitryl phenyl) methylenimine as areaction raw material, the alpha-glucosidase inhibitor is synthesized successfully through three reaction steps: carbonylation reaction, reduction reaction and sulfonation reaction. The method has the characteristics of being novel in synthetic means, simple to operate, excellent in yield and the like.
Method for one-pot synthesis of alpha-glucosidase inhibitor by carbonylation reaction
-
Paragraph 0030; 0031; 0032, (2017/10/10)
The invention relates to a method for one-pot synthesis of an alpha-glucosidase inhibitor by carbonylation reaction. The method employs 4-nitrobenzaldehyde and n-butylamine as the reaction raw materials to carry out amine-aldehyde condensation, oxidative carbonylation reaction, nitro group reduction and sulfonation reaction so as to successfully synthesize the alpha-glucosidase inhibitor. The method has novel synthesis means, successfully synthesizes the alpha-glucosidase inhibitor by carbonylation reaction, and has the advantages of simple and easily available reaction raw materials, mild reaction conditions, and good atom economy and step economy of reaction, thus according with the development requirements of green chemistry.
