This graphical review provides a concise overview of transition-metal-catalyzed asymmetric
reduction of 2-pyridine ketones to produce enantiopure chiral 2-pyridine aryl/alkyl
alcohols, which are present in many chiral ligands and pharmaceuticals. Key methods
include metal-catalyzed hydrogenation, transfer hydrogenation, and hydrosilylation,
with a focus on sustainable catalysts like iron and manganese. This review serves
as a foundation for future advancements in sustainable and enantioselective keto group
reductions.
