To Professor Kenji Uneyama and Professor Donald J. Burton for their great contribution to fluoroorganic chemistry

Abstract

Pyrrolidines and their derivatives are of great interest in medicinal chemistry and organic synthesis. Fluoropyrrolidines and (fluoroalkyl)pyrrolidines have been utilized in the preparation of medicinal drugs and also as organocatalysts. The synthesis of such compounds is achieved through the fluorination of pyrrolidine derivatives or by multistep synthesis from already containing fluoroalkyl precursors.
