Synthesis of β-Amino Acids and Derivatives


Recent Literature

An efficient asymmetric 1,4-addition of arylboronic acids to β-phthaliminoacrylate esters was realized by use of a hydroxorhodium/chiral diene complex to give high yields of β-aryl-β-amino acid esters with excellent enantioselectivity.
