Abstract By using planar chiral [2.2]paracyclophane-containing N,O-chelating ligands for tantalum-catalyzed hydroaminoalkylation, one of the most versatile catalytic systems for this reaction to date was obtained. Convenient Csp3−Csp3 bond formation of amines with terminal and internal alkenes was enabled by the same in situ synthesized catalytic system of [2.2]paracyclophane-based pyridonates and Ta(CH2TMS)3Cl2 that shows also very promising results for N-containing heterocycles.
