Chiral Phosphanylferrocenecarboxamides with Amino Acid Pendant Groups as Ligands for Cu-Mediated Asymmetric Conjugate Additions of Diethylzinc to Chalcones – Structural Characterisation of Precursors to the Cu Catalyst
2010
Abstract
A series of chiral phosphanylferrocenecarboxamides with amino acid pendant groups was prepared and tested as ligands to Cu-catalysed enantioselective conjugate addition of diethylzinc to chalcones. Precursors to the Cu catalysts were structurally characterised.
