perazine-bridged CCR5 antagonists were designed and synthesized via an efficient convergent synthesis strategy, with focus on the optimal choice of the basic center carrier structure. Significantly, the 4-amino-4-methylpiperidine bridged 1-acyl-1,3-propanediamine compounds were identified as a new class of nanomolar CCR5 antagonists, providing an efficient approach and novel scaffolds for further development

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)-β3-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.
