摘要:
Disclosed is a method for synthesizing a novel chiral ligand, a metal chelate, a variety of non-natural amino acids, Maraviroc and a key intermediate thereof. In the invention, (R)-2-methyl proline is selected and used as a starting raw material, (S)-β 3 -amino acid is obtained by asymmetric resolution induced by using a nickel chelate, and Maraviroc is synthesized by using (S)-3-amino-3-phenylpropionic acid as a key intermediate with a high yield and the ee value reaching 98.2% or more. The method of the present invention has widely available materials, mild synthetic process conditions, is easy to control, and produces a product of a high optical purity.
摘要:
A polymorph of (R) methyl-2-(3-aminopiperidin-1-yl)-3-(2-cyanobenzyl)-4-carbonyl-3,4-dihydrothioph ene[3,2-d]pyrimidine-6-carboxylic acid maleate and a preparation method therefor. The polymorph is a crystal having high stability and low hygroscopicity, and the crystal form is selected from crystal form A, crystal form B and crystal form C. Furthermore, the crystal form has a strong in-vivo hypoglycemic activity and can be used for the preparation of a novel drug for the treatment or prevention of diabetes mellitus type H and/or complications of diabetes mellitus type H.
