Chiral pyridyl alcohols are a type of synthetically versatile building block for natural products, functional materials and bioactive molecules. Herein, a highly efficient Ir/f-amphox-catalyzed asymmetric hydrogenation of 1-(pyridin-2-yl)ketone derivatives to access chiral pyridyl alcohols was reported. The reaction proceeds smoothly under mild conditions, delivering excellent yields and enantioselectivities (up to >99% ee, turnover number (TON) up to 2000). A broad range of pyridyl alkyl and aryl ketones were successfully transformed, demonstrating the generality and synthetic utility of this methodology.

Key words: asymmetric hydrogenation, f-amphox, pyridyl alcohols
