Catalytic Asymmetric Intramolecular Hydroamination of Alkynes in the Presence of a Catalyst System Consisting of Pd(0)-Methyl Norphos (or Tolyl Renorphos)-Benzoic Acid

Enantiomerically pure methyl Norphos (A), tolyl Norphos (B), CF3 Norphos (C), methyl Renorphos (D), and tolyl Renorphos (E) were synthesized and used as chiral bisphosphine ligands for the catalyst system, Pd2(dba)3·CHCl3/PhCOOH, in an intramolecular hydroamination of aminoalkynes 15. Among the Norp...
