The first catalytic asymmetric synthesis of highly functionalized pentafluorosulfanylated pyrrolidines is described. The method, based on a 1,3‐dipolar cycloaddition reaction of aryl and heteroaryl‐substituted glycine Schiff bases with pentafluorosulfanyl acrylic esters, gave access to a broad range of pyrrolidines bearing aryl, naphtyl, and heteroaryl groups. By using Xing‐Phos as a catalyst, the
