ruthenium‐catalyzed formal anti‐Markovnikov hydroamination of allylicalcohols for the synthesis of chiral γ‐amino alcohols is presented. Proceeding via an asymmetric hydrogen‐borrowing process, the catalysis allows racemic secondary allylicalcohols to react with various amines, affording enantiomerically enriched chiral γ‐amino alcohols with broad substrate scope and excellent enantioselectivities (68 examples

The first example of Mn-catalyzed asymmetric formal anti-Markovnikov hydroamination of allylic alcohols is described by using a chiral peraza N6-macrocyclic ligand. DFT calculations revealed that multiple noncovalent interactions existed among the ligand, solvent, and substrate in the transition states, showing a remarkable macrocyclic ligand effect.
