An Efficient Asymmetric Biomimetic Transamination of α‑Keto Esters to Chiral α‑Amino Esters

An efficient asymmetric biomimetic transamination of α-keto esters with quinine derivatives as chiral bases was described. A wide variety of α-amino esters containing various functional groups can be synthesized in high yield and enantioselectivity
