Abstract

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 as the rate-determining step.
