Title: Amleto Rizzi: Innovator in Pharmaceutical Chemistry
Introduction
Amleto Rizzi is a notable inventor based in Alte Ceccato, Italy. He has made significant contributions to the field of pharmaceutical chemistry, particularly in the synthesis of optically active compounds. With a total of 2 patents, Rizzi's work focuses on processes that enhance the efficiency and effectiveness of drug development.
Latest Patents
Rizzi's latest patents include a process for the optical resolution of threo-2-hydroxy-3-(2'-aminophenylthio)-3-(4'-methoxyphenyl)-propionic acid. This invention is crucial for separating the enantiomers of this compound, which serves as an important intermediate in synthesizing pharmacologically active substances. The process involves the direct crystallization of the relevant cyclohexylaminic salt, ultimately recovering the optically pure acid as the hydrochloride of the corresponding methyl ester.
Another significant patent by Rizzi pertains to a novel process for synthesizing 2-aryl-3-hydroxy-cis-2,3-dihydro-1,5-benzothiazepin-4(5H)-ones and their derivatives. This invention allows for the production of optically pure compounds or their racemic mixtures using methyl esters of 2-hydroxy-3-arylthio-3-arylpropionic acids as synthesis precursors. The process involves treating these precursors with an excess of sodium methoxide at low temperatures in various solvents.
