Interaction between chiral ligands and substrates in asymmetric catalysis;

Synthesis of chiral ligands from aminophenol derivatives

The research advances of the chiral ligands metal complexes catalysts used in asymmetric 1,3-dipolar cycloaddition reactions were reviewed in this paper.

And then the chiral monomers of N-acyl amino acid esters were synthesisedvia esterification of Boc-L-amino acid,mentioned above,with acryl alcohol catalyzed by 4-dimethylamino pyridine and 1,3-dicyclohexylcarbodiimide.

Polymers P1~P8 were synthesized by graft copolymerization of mesogenic monomer cholesteryl undecylenate (M1) and chiral monomer menthyl acrylate (M2) upon polymethylhydrosiloxane.

Particularly, general approaches to the formation of asymmetric glycerophospholipid skeletons by utilizing stereospecific reactions and chiral precursors are dis-- cussed.

In the present review, we describe the asymmetric synthesis via the reactions of chiral crystals of achiral molecules.
