Title: The Innovative Work of Jacques Defaye in Glycoside Chemistry
Introduction
Jacques Defaye, an accomplished inventor based in Saint Dismier, France, has made significant contributions to the field of glycoside chemistry. With a total of four patents to his name, Defaye's work focuses on the preparation and application of innovative chemical processes, particularly those involving alkyl glycosides and their derivatives. His research has implications for various industries, including food and biochemistry.
Latest Patents
Defaye's most recent patents showcase his pioneering approaches. One notable patent details a process for preparing alkyl-1-thioglycosides and alkyl glycosides. This innovation involves reacting a selected saccharide, such as monosaccharides and reducible di- and oligo-saccharides, with either a thiol or an alcohol in the presence of poly-(hydrogen fluoride)-pyridinium. The resulting alkyl-1-thio-.alpha.,.beta.-glycosides, characterized by a mixture of .alpha. and .beta. anomers, serve as effective nonionic detergents, especially in the extraction of membrane proteins.
Another patent pertains to a process for cyclo-dehydrating ketoses to obtain anhydrides and their uses. This method involves reacting glucides that contain a ketose group without adding water, utilizing a hydrogen halide that is subsequently evaporated to collect disaccharide anhydride. The resulting products, which typically consist of saccharide anhydrides that include fructose cycles, are potential food additives, further highlighting Defaye's impact on food chemistry.
