Title: Weiguo Liu: Innovator in Chemical Processes

Introduction

Weiguo Liu is a notable inventor based in Buffalo Grove, IL (US). He has made significant contributions to the field of chemistry, particularly in the development of innovative processes for chemical synthesis. With a total of 2 patents, Liu's work showcases his expertise and creativity in the realm of chemical engineering.

Latest Patents

Liu's latest patents include a method for stereoselectively inverting a chiral center of a chemical compound using an enzyme and a metal catalyst. This process involves forming a mixture of the chemical compound, an enzymatic system, and a metal catalyst. The method then stereoselectively dehydrogenates a group attached to the chiral center with the enzymatic system in the presence of an oxidant, producing a dehydrogenated group. Finally, the process hydrogenates the dehydrogenated group with the metal catalyst in the presence of a hydrogen source to stereoselectively invert the chiral center of the chemical compound.

Another significant patent is the synthesis of optically active phenylalanine analogs using Rhodotorula. This biocatalytic process produces optically active phenylalanine analogs from arylacrylic acids. In this process, Rhodotorula graminis yeast containing phenylalanine ammonia-lyase introduces a molecule of ammonia stereoselectively onto the double bond of a 3-substituted acrylic acid. The substituent at the 3-position of the 3-substituted acrylic acid includes various aromatic rings and heterocycles.
