An efficientpalladium‐catalyzed regioselective 5‐exo aminotrifluoromethoxylation of alkenes has been established herein, which provides a practical route towards the synthesis of OCF3‐containing pyrrolidines. tert‐Butyloxycarbonyl (Boc) as an amino protectinggroup plays a significant role in both the chemo‐ and regioselectivities. In addition, preliminary mechanistic studies reveal that the amino
