Abstract
An iridium catalyst (2.5 mol %) generated in situ from [Ir(coe)2Cl]2 and a nitrogen phosphorus ligand was efficient in the asymmetric ring-opening reactions of low-activity azabenzonorbornadiene with various aliphatic and aromatic amines, providing the corresponding chiral vicinal 1,2-diamine scaffolds in high yields (up to 98%) and excellent enantioselectivities (up to 97% ee). The synthetic utility of the transformation was demonstrated by performing a gram-scale reaction.
