Given the growing demand for enantiomerically enriched compounds, the design of efficient,
atom-economical, and sustainable synthetic strategies for the preparation of chiral
alcohols and amines remains a critical objective in modern chemistry. This short,
updated review highlights recent advances in homogeneous asymmetric catalysis employing
transition-metal complexes in asymmetric hydrogenation (AH) and transfer hydrogenation
(ATH) of ketones and imines under dynamic kinetic resolution (DKR) conditions to access
these important building blocks. These methods enable the simultaneous formation of
multiple stereogenic centers and have been significantly expanded through the development
of novel catalytic systems and their application to previously unexplored classes
of substrates.
