The use of a non-C2-symmetric ProPhenol ligands enables a catalytic and asymmetric vinylation of N-Boc imines via hydrozirconation providing allylic amines in excellent yields and enantioselectivities. A very short, asymmetric synthesis of the selective serotonine reuptake inhibitor (SSRI) (-)-dapoxetine is also reported.
