摘要
The direct asymmetric reductive amination (DARA) of ketones with anilines is described by combining a chiral Bronsted acid (TRIP) and the non-chiral Knolker iron complex as the catalyst system. In situ-formed imines are reduced with molecular hydrogen to give chiral amines in high yields (90%) and enantioselectivities of up to 99% ee.
