Abstract: The use of easily accessible N-monosubstituted 1,2-diphenyl-2-aminoethanols as ligands to promote the asymmetric addition of diethylzinc to alkyl- and arylimines generated in situ from the precursors provided optically active N-diphenylphosphinylamines with enantioselectivities of up to 96% ee.
