| Abstract: | Chiral dendrimers bearing three or six chiral β-amino alcohols on the hyperbranched hydrocarbon chain-ends act as efficient chiral ligands for the enantioselective addition of diethylzinc to N-diphenylphosphinylimines to afford enantiomerically enriched N-diphenylphosphinylamines with up to 94% e.e. |
