Title: Innovations of Douglas Sawyer

Introduction

Douglas Sawyer is an accomplished inventor based in Gilbert, AZ (US). He has made significant contributions to the field of chemistry, particularly in the synthesis and resolution of nicotine. With a total of three patents to his name, Sawyer's work has implications for both pharmaceutical applications and the understanding of nicotine's enantiomers.

Latest Patents

One of Sawyer's latest patents focuses on the synthesis and resolution of nicotine. This patent outlines methods for preparing nicotine and resolving R,S nicotine to enrich the (S)(−) enantiomer. The process involves combining N-methyl-2-pyrrolidone or a salt thereof with a nicotinate compound in the presence of a solvent and a strong base. This results in the formation of 1-methyl-3-nicotinoyl-2-pyrrolidone or a salt thereof. The subsequent reduction of this compound in solution with NaSO produces racemic nicotine or its salt. The resolution of racemic nicotine may involve combining it with (−)-O,O'-di-p-toluoyl-L-tartaric acid (L-PTTA).
