Boron trifluoride-mediated transformation of tetrahydrofuran to corresponding N-aryl-substituted pyrrolidines is conducted under mild reaction conditions, providing a practical synthetic method with reasonable yields. Computational studies confirmed the reaction mechanism involving a fast Lewis acid-assisted ring-opening step, followed by the 7-membered intermediate formation and a ringclosing process
