title: Hydroxoiridium/Chiral Diene Complexes as Effective Catalysts for Asymmetric Annulation of α-Oxo- and Iminocarboxamides with 1,3-Dienes.
abstract: The asymmetric [3+2] annulation of α-oxo- and α-iminocarboxamides with 1,3-dienes catalyzed by hydroxoiridium/chiral diene complexes was realized, giving high yields of the corresponding γ-lactams with high enantioselectivity.
