A general protocol for the preparation of enantioenriched α-tetrasubstituted α-trifluoromethyl homoallylic amines is disclosed. Despite the significant challenge in stereoselectivity control, Ir-catalyzed asymmetric cascade umpolung allylation/2-aza-Cope rearrangement of trifluoromethylated fluorenone imines with allylic carbonates was realized with excellent efficiency and remarkable stereoselectivity. These were enabled by the suitable protective imino moiety and an unexpectedly exclusive E-geometrical imine of the allylation intermediate. This methodology is also applicable to facile access to chiral α-trisubstituted α-trifluoromethyl homoallylic amines in similarly high yield and stereoselectivity.
