The iridium-catalyzed asymmetric hydrogenation of N-phenyl-β- dehydroamino acid derivatives was examined using monodentate phosphoramidite ligands. The highest yields and enantioselectivities were obtained using a mixed ligand approach with PipPhos L1 and
Production method for optically active N-aryl-beta-amino acid compounds

In a method suitable for industrial application, an optically active N-aryl-β-amino acid compound is produced by the reaction of an aromatic amine and an optically active sulfonylated β-hydroxycarboxylic acid compound. The latter can be easily derived from a β-keto carboxylic acid compound.
Pd/Cu-catalyzed couplings of β-amino esters with aryl bromides. Synthesis of chiral 1,2,3,4-tetrahydro-4-oxo-2-alkyl-1-quinolines

A new protocol to prepare chiral 1,2,3,4-tetrahydro-4-oxo-2-alkyl-l- quinolines has been developed. The key steps are Pd/Cu-catalyzed couplings of chiral β-amino esters and aryl bromides, and intramolecular acylation.
