Abstract

Abstract: The covalent combination of the thiazolium hetero- cycle of thiamine with macrotricyclic quaternary ammonium receptor units yields the enzyme mimics 3a,b, which show enhanced substrate selectivity and catalytic activity in decarboxylations of a-ketoacids compared to simpler salts lacking the receptor substructure. ... In contrast to the great variety of enzyme models for hydrolytic or redox reactions, artificial mimics of biological carbon-carbon bond forming or ...
