The benzylic substituted P,N ligands, diphosphinobenzyloxazolines, showed their high catalytic activity as well as asymmetric induction in the iridium‐catalyzed asymmetric hydrogenation of unfunctionalized alkenes, α,β‐unsaturated esters, allyl alcohols, α,β‐unsaturated ketones, and imines, providing the corresponding chiral products in high ee with high conversion.
