Abstract
Chiral phosphoric acids have been identified as highly efficient organocatalysts for the asymmetric transfer hydrogenation of α‐imino esters and amide. Utilizing Hantzsch esters as the hydrogen donor, versatile highly enantioenriched α‐amino esters and their derivatives were obtained with up to 98 % ee.
