The synthesis of six members of the HetPHOX ligand class and the application of palladium complexes of these ligands to the intermolecular asymmetric Heck reaction is described. The tert-leucinol-derived ligands proved the most enantioselective, with palladium complexes of these ligands affording ee values of up to 96, 95 and 94 % in the phenylation, cyclohexenylation and naphthylation, respectively
