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

A novel Pd-catalyzed enantioselective aminochlorination of alkenes via a 6-endo cyclization is reported herein, which provides easy access to a wide array of structurally diverse 3-chloropiperidines in good yields with excellent enantioselectivities. Notably, both an electrophilic chlorination reagent (NCS) and the sterically bulky chiral pyridinyl-oxazoline (Pyox) ligand are crucial to the successful
