Planar‐Chiral [2.2]Paracyclophane‐Based Pyridonates as Ligands for Tantalum‐Catalyzed Hydroaminoalkylation

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.
