Asymmetric methods to prepare optically active a-chiral primary amines are highly demanded in asymmetric synthesis owing to the biological/pharmacological activity of many amines.[1] Various techniques have been reported, such as asymmetric 1, 2-addition to imines and asymmetric amination of a, a-disubstituted aldehydes,[2] transformation of allylic alcohols into amines,[3](dynamic) kinetic resolution,[4] and cyclic deracemization [5] ...
