Anti‐Markovnikov Hydroamination of Racemic Allylic Alcohols to Access Chiral γ‐Amino Alcohols

A ruthenium‐catalyzed formal anti‐Markovnikov hydroamination of allylic alcohols for the synthesis of chiral γ‐amino alcohols is presented. Proceeding via an asymmetric hydrogen‐borrowing process, the catalysis allows racemic secondary allylic alcohols to react with various amines, affording enantio...

Zusammenfassung:A ruthenium‐catalyzed formal anti‐Markovnikov hydroamination of allylic alcohols for the synthesis of chiral γ‐amino alcohols is presented. Proceeding via an asymmetric hydrogen‐borrowing process, the catalysis allows racemic secondary allylic alcohols to react with various amines, affording enantiomerically enriched chiral γ‐amino alcohols with broad substrate scope and excellent enantioselectivities (68 examples, up to >99 % ee). Anti‐Markovnikov hydroamination of racemic allylic alcohols produces chiral γ‐amino alcohols, which are key intermediates for the synthesis of many drugs and biologically active molecules. Driven by a ruthenium catalyst via a hydrogen borrowing pathway, the reaction features a broad substrate scope (68 examples) and excellent enantioselectivities (up to >99 % ee).
