Pd-catalyzed asymmetric allylic aminations with aromatic amine nucleophiles using chiral diaminophosphine oxides: DIAPHOXs
摘要:
Asymmetric allylic aminations with aromatic amine nucleophiles using Pd-DIAPHOX catalyst systems are described. The asymmetric allylic aminations of various allylic carbonates proceeded using 2-5 mol % of the catalyst and BSA, providing the corresponding N-aryl chiral allylic amines in up to 99% ee for cyclic substrates, and in up to 97% ee for acyclic substrates.
