Iridium‐catalyzed asymmetric hydrogenation of β‐ketophosphonates with chiral ferrocenyl P,N,N‐ligands

The asymmetric hydrogenation of β‐ketophosphonates with chiral Ir/P,N,N‐ligands catalyst has been developed. A series of β‐ketophosphonates were hydrogenated, and the corresponding β‐hydroxyphosphonates were obtained in high yields with good or excellent enantioselectivities under mild condition.
