Kinetic resolution of chiral aminoalkenes via asymmetric hydroamination/cyclisation using binaphtholate yttrium complexes

Abstract

Chiral binaphtholate yttrium aryl complexes are highly active and enantioselective catalysts for the asymmetric hydroamination of aminoalkenes, as well as the kinetic resolution of α-substituted 1-aminopent-4-enes to give trans-2,5-disubstituted pyrrolidines with good enantiomeric excess and high k_rel.
