privileged chiral skeleton for chiralligand design bearing central/planar chirality, and such ligands have exhibited tremendous success in various asymmetriccatalysis. However, the current access to enantiopure Ugi’s amine is quite tedious and relies heavily on optical resolution, which impedes its practical applications, to some extent. Herein, we present a facile asymmetricsynthesis of enantioenriched
