Iridium-Catalyzed [3+2] Annulation of Cyclic N-Sulfonyl Ketimines with 1,3-Dienes via C-H Activation

Ir-catalyzed [3 + 2] annulation of cyclic N-sulfonyl ketimines with 1,3-dienes, in which an aryliridium intermediate is formed via C-H activation, gives amino-indane derivatives in high yields with high regio- and diastereoselectivity.
