Author: Su, Cunxiang, Xie, Ying, Pan, Hongjie, Liu, Mao, Tian, Hua, and Shi, Yian
Subjects: *BIOMIMETIC materials, *ESTERS, *CHIRALITY
Abstract: An asymmetric biomimetic transamination process for β-branched α-keto esters (I) with a hydroquinine-derived chiral base and 4-cyano-benzylamine as the nitrogen source is reported. A wide range of branched α-amino esters (II) is obtained in 50--96% yield and 87-- 95% enantioselectivity. [ABSTRACT FROM AUTHOR]
