Iridium-Catalyzed [3 + 2] Annulation of Cyclic <i>N</i>‑Sulfonyl Ketimines with 1,3-Dienes via C–H Activation

Abstract

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