Abstrakt:	A new representative of P*-monodentate bicyclic amidophosphite ligands of 2,6-dioxa-7-aza-1-phosphabicyclo[2.2.1]heptane series and its complex [Pd(allyl)(L)Cl] were obtained. Newly synthesized compounds were thoroughly characterized by 31P{1H}, 1H, and 13C{1H} NMR spectroscopy and 2D NMR experiments. The structure of the ligand was confirmed by X-ray diffraction analysis. Palladium catalysts derived from this chiral inductor provided up to 50% ee in asymmetric amination of (E)-1,3-diphenylallyl acetate with pyrrolidine. [ABSTRACT FROM AUTHOR]
