Title: The Innovative Contributions of Tamotsu Asano

Introduction

Tamotsu Asano, an accomplished inventor based in Chiba, Japan, has made significant strides in the field of chemical engineering. With a remarkable portfolio of nine patents, Asano has developed novel processes that enhance the production and purification of various chemical compounds.

Latest Patents

Among Asano's latest innovations are two noteworthy patents. The first, a "Method of purifying amide compound," outlines a process for effectively removing impurities from an amide compound-containing solution. This process leverages the interaction between the solution, specifically those produced by hydration reactions of nitrile compounds, and a microorganism fungus body containing nitrile hydratase in contact with activated carbon under acidic conditions.

The second patent details a "Process for selectively producing 1-phosphorylated sugar derivative anomer and process for producing nucleoside." This innovative method allows for the selective preparation of desired isomers via phosphorolyzing and isomerizing an anomer mixture of a 1-phosphorylated saccharide derivative. By crystallizing one of the isomers, the equilibrium can be efficiently displaced. Additionally, a nucleoside is prepared through the action of a nucleoside phosphorylase, resulting in improved stereoselectivity and yield.
