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.
苄基取代的P,N配体二膦基苄基恶唑啉在铱催化的未官能化烯烃,α,β-不饱和酯,烯丙醇,α,β-不饱和酮和亚胺的铱催化的不对称氢化中表现出高催化活性以及不对称诱导作用。提供相应的手性产品在高ee值与高转化率。
