Title: Jouji Sekine: Innovator in Pharmaceutical Chemistry

Introduction

Jouji Sekine is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of pharmaceutical chemistry, particularly in the production of optically active compounds. With a total of 3 patents to his name, Sekine's work is recognized for its potential applications in drug manufacturing.

Latest Patents

Sekine's latest patents focus on the process for producing highly pure optically active threo-3-amino-1,2-epoxy compounds. These compounds are essential materials for manufacturing drugs. The process involves subjecting an optically active threo-3-amino-1,2-diol derivative in an organic solvent, along with a base, to alkylsulfonylation or arylsulfonylation. This results in the corresponding optically active threo-3-amino-2-hydroxy-1-sulfonyloxy compound. The subsequent step includes epoxidation in the presence of a base, yielding the desired optically active threo-3-amino-1,2-epoxy compound. The final product is purified using an organic solvent and water, resulting in a highly pure epoxy compound.
