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