Development and Scale-up of an Organocatalytic Enantioselective Process to Manufacture (<i>S</i>)-Pregabalin

Abstract

Herein is reported the development of a new process to manufacture (S)-pregabalin. The method comprises six steps, run under the catalysis of a recyclable polymer bound phase transfer catalyst, and afforded (S)-pregabalin in overall 54% yield, starting from building blocks acetylacetone, isovaleraldehyde, and nitromethane.
