Title: Innovations by Jeffrey A. Levine in Amino Carboxylic Acid Preparation
Introduction: Jeffrey A. Levine is a distinguished inventor based in University City, Missouri, who has made significant contributions to the field of chemistry through his innovative patents. With a total of two patents, Levine has focused on developing methods for synthesizing amino carboxylic acids, which are valuable in various biochemical applications.
Latest Patents: Levine's latest patents include a method for preparing novel compounds such as N,N'-bis(phosphonomethyl)-N,N'-bis(hydroxycarbonylmethyl)urea and N,N,N',N'-tetrakis(hydroxycarbonylmethyl)urea. These compounds are particularly suitable for the preparation of N-acyl aminocarboxylic acids, which can be converted to N-(phosphonomethyl)glycine. The process involves a chemical reaction in which bis-(phosphonomethyl)urea or urea reacts with carbon monoxide and formaldehyde using a carboxymethylation catalyst precursor in a solvent.
The second patent outlines a process for the preparation of N-acyl amino carboxylic acids via a carboxymethylation reaction. This innovative method creates a reaction mixture containing a base pair, carbon monoxide, hydrogen, and an aldehyde. The base pair is made up of a carbamoyl compound and a carboxymethylation catalyst precursor, ultimately yielding an N-acyl amino carboxylic acid that can be easily converted to N-(phosphonomethyl)glycine or its salts and esters.
Career Highlights: Jeffrey A. Levine is currently affiliated with the Monsanto Company, where he has furthered his research and development efforts. His work has contributed to advancements in agricultural sciences, especially through the synthesis of compounds that may enhance crop production and protection.
