Abstract
The synthesis of a new class of modular chiral phosphino-oxazoline ligands containing the diphenylphosphino group at different positions of the heterocyclic backbone is described. HetPHOX ligands were tested in enantioselective allylations and in transfer hydrogenation reactions. The synthesis of the ligands is facile with high enantioselectivity (99% ee) obtained in the Pd-catalyzed addition of malonate to diphenylallyl acetate using ligand 10.
