Angewandte Chemie, EarlyView.Benzamide‐directed iridium‐catalyzed branched selective and enantioselective C(sp2)‐H additions to minimally activated alkenes give tertiary and quaternary benzylic stereocenters under byproduct‐free conditions. The processes are enabled by a family of SPINOL‐based homochiral diphosphonite ligands.
