Several derivatives of ferrocene ligands with planar chirality were investi
gated in palladium-catalysed asymmetric allylic alkylation of iminoesters,
in which bis-ferrocene ligand 7 containing a chiral pocket showed good enan
tiocontrol in this reaction; the products having a quaternary chiral center
were obtained with up to 75.3% ee.
