Catalysis of Cope-type rearrangements of bis-homoallylic hydroxylamines is demonstrated using chiral thiourea derivatives. This formal intramolecular hydroamination reaction provides access to highly enantioenriched alpha-substituted pyrrolidine products and represents a complementary approach to metal-catalyzed methods.
